Hydraulic fracturing is a very important technique to increase the productivity and recovery of oil reservoirs with low pressure or high depth. The hydraulic fracturing technique is a method of well stimulation in which liquid under high pressure is pumped down a well to fracture the reservoir rock adjacent to the wellbore. Propping agents are used to keep the fractures/cracks open. They can be made from the reject of mineral extraction processes when they present specifics characteristic. The aim of this paper is the evaluation of the use of industrial rejects to the development of ceramic synthetic proppants that are resistant to chemical corrosion and high mechanical strength in aqueous acid and salt water environment. In this study, industrial rejects from nickel sulfide ore flotation (grey mud - GM), red mud (RM) from Bayer process and black mud (BM) from Caron processing of nickel was used as raw material for the production of ceramic synthetic proppants. The material processing was performed through drying, milling, pressing, sintering and characterizing raw material. Several characterization techniques such as X-ray powder diffraction (XRD), Differential Scanning Calorimetry (DSC), Scanning Electron Microscopy (SEM), high temperature dilatometry and compression strength test were performed after sintering to evaluate the technological potential of recycling these metallurgical and mineral rejects. Mechanical properties were improved after sample sintering. The results show that it is possible to manufacture ceramics of high strength and resistance to acidic/salt water environment as a result of processing minerals reject.; CAPES; Votorantim Metals; CBA

Apresenta-se aqui a caracterização do filito e a avaliação da sua aplicação como carga mineral na produção de materiais plásticos. Amostras de jazidas em lavra no município de Itapeva, sudoeste do Estado de São Paulo, foram preparadas em laboratório, através de secagem e peneiramento, e analisadas física e quimicamente, sendo comparadas com outros minérios utilizados comumente como cargas minerais. Uma dessas amostras, após sua preparação, foi aplicada como carga na produção de peças plásticas no Centro Técnico de Serviços CTS da empresa Braskem S.A., a partir de pastas formadas com PVC e plastificantes, conhecidas como plastisóis. O filito foi incorporado em varias formulações de compostos utilizados para produção de bolas plásticas comuns. Os resultados, em termos de resistência mecânica, foram comparados com os de compostos contendo carbonato de cálcio natural, moído, em malha inferior a 44 m. O carbonato de cálcio natural, ou calcita, constitui a carga mais tradicionalmente utilizada nesse setor industrial. Os testes realizados indicaram que o filito confere ao material polimérico produzido, composto de polímeros, aditivos e cargas, propriedades desejáveis de resistência mecânica e acabamento...

The pegmatite rocks in Rio Grande do Norte are responsible for much of the production of industrial minerals like quartz and feldspar. Quartz and feldspar are minerals from pegmatite which may occur in pockets with metric to centimetric dimensions or as millimetric to sub millimetric intergrowths. The correct physical liberation of the mineral of interest, in case of intergrowths, requires an appropriate particle size, acquired by size reduction operations. The method for treating mineral which has a high efficiency fines particles recovery is flotation. The main purpose of the present study is to evaluate the recovery of quartz and potassium feldspar using cationic diamine and quaternary ammonium salt as collectors by means of dissolved air flotation DAF. The tests were performed based on a central composite design 24, by which the influence of process variables was statistically verified: concentration of the quaternary ammonium salt and diamine collectors, pH and conditioning time. The efficiency of flotation was calculated from the removal of turbidity of the solution. Results of maximum flotation efficiency (60%) were found in the level curves, plotted in conditions of low concentrations of collectors (1,0 x 10-5 mol.L-1). These high flotation efficiencies were obtained when operating at pH 4 to 8 with conditioning time ranging from 3 to 5 minutes. Thus...

Endosperm hardness is an essential attribute for producers and industries that using corn as a raw material. Kernel texture alterations, however, hamper the commercial use of Quality Protein Maize (QPM). In this experiment, industrial yield was compared in kernel degerming and endosperm splitting and the nutritional value of a QPM variety and common corn genotypes. One QPM variety and three commercial corn hybrids cultived in Goiás were studied. The QPM and the common corn hybrids were processed using the dry degerming method and the resulting yield was expressed as the ratio of the weight of the fractions obtained to the initial weight of the whole corn. The chemical composition and the amino acid profile of QPM, common corn and common corn germ were determined and an experiment with recently weaned Wistar rats was carried out. Four 7 %-protein and one nonprotein diet were prepared. Protein utilization was estimated using the DCF (Dietary Conversion Factor), NPR (Net Protein Ratio), True Digestibility, and the PDCAAS (Protein Digestibility- Corrected Amino Acid Score). In comparison with common corn, QPM presented lower endosperm yield, higher germ and fine fractions (< 0.5 mm) yield, and the same yield for hominy in endosperm splitting. QPM presented similar levels of proteins...

This Note examines the potential of the mining sector to be a source of growth for the Afghanistan economy. In order to address this fundamental and strategic issue, this Note will ask and provide answers to three principal questions. First, what is the potential in Afghanistan for large and small scale minerals development? Second, given the potential, what are the constraints for development of the sector in terms of the enabling environment (policy, regulatory, taxation) for private investment, institutional capacities, infrastructure and other constraints? And, third, what would be a reasonable sector development scenario over the next five years and what could be the benefit streams (production value, taxes, jobs, value added, etc.) generated under such a scenario? It is intended that the Note serve as a baseline document to help the government reflect on sector policies and strategies and to provide a "roadmap" for development of the sector. The roadmap will help the government to know where it wishes t o go...

The in-situ mineral characteristics of a deposit are simulated by sequential co-simulation and averaging the simulated characteristics within specified block volumes creates a three-dimensional block model. This model is then submitted to optimal open pit and production scheduling algorithms. As the market values of industrial minerals depend on the satisfaction of predetermined blending criteria rather than metal content, a Linear Programming (LP) scheme has been used to identify all blocks that can be included in the blend without violating the grade requirements. The Lerchs-Grosmann algorithm using the blocks identified by the LP program determines optimal pit limits. All blocks that lie outside the optimal pit are removed from the system and the blocks within the optimal pit are submitted to the production-scheduling algorithm. Production scheduling optimisation is done in two stages: Lagrangean parameterisation, resulting in an initial sub-optimal solution, and multi-objective simulated annealing (MOSA) improving the sub-optimal schedule further.; http://trove.nla.gov.au/work/16261027

Indiana Geological Survey Bulletin 31; Modern concepts of clays as assemblages of discrete minerals form the basis for the first reevaluation of the clays and shales of Indiana since 1933. Brief explanations of the fundamentals of clay mineralogy and the major methods of investigation of clays enable the reader to understand more fully the data obtained. Tabulated mineralogic, ceramic, and chemical data for 251 samples chosen from about 1, 000 samples give a perspective of the types, properties, and locations of clays in Indiana. These data reveal that Indiana has large reserves of clay suitable as raw material for many types of products. The most notable reserves are several abundant clays and shales for manufacturing structural clay products and cement, the Pennsylvanian underclays for use in refractories and structural clay products, and certain shales, such as the New Providence Shale, for producing lightweight aggregate.; Indiana Department of Conservation

Indiana Geological Survey Bulletin 42-D; Sand and gravel are unconsolidated granular materials resulting from the natural disintegration of rocks. Unlike most other mineral commodities they are defined in terms of particle size rather than mineral or chemical composition. In general, sand is a detrital material consisting of rock and mineral fragments that are less than 2 millimeters and greater than one-sixteenth millimeter in diameter. Gravel is a coarse detrital material consisting of rounded or partly rounded fragments of rocks and minerals greater than 2 millimeters in diameter. The upper size range, although variable, is considered to be 3 ½ to 4 inches. Sand and gravel are used in large quantities as a base or sub-grade material for highways, as roadstone on unpaved roads and as fill material. Another important use is as aggregate or the framework component in concrete, mortar, or bituminous mixes. Each year vast quantities of sand and gravel are used in making highways, bridges, dams, runways, foundations, and buildings. During 1968 sand and gravel production in Indiana, exclusive of specialty sands, was 25,774,000 tons and was valued at $26,160,000.; Indiana Department of Natural Resources

Indiana Geological Survey Report of Progress 8; This investigation was undertaken to make the features of evaporites (gypsum and anhydrite) in southwestern Indiana known and to determine their origin, geologic occurrence, uses, and relationship to associated rock strata. A detailed study of evaporites in Indiana has never been undertaken. In fact, it was not known until recently that relatively thick beds existed in the state. Evaporites, however, are not new among the minerals found in Indiana; they have been observed in well cuttings and as nodular masses and thin beds in outcrops. Logan reported that a thin bed of gypsum (selenite) crops out between the Beaver Bend limestone and Sample sandstone in a railroad cut east of Huron, Lawrence County. Gypsum also occurs commonly as nodular masses in the Harrodsburg and St. Louis limestones and in many places forms a conspicuous part of their lithology. Moreover, as stated above, subsurface studies in southwestern Indiana have revealed rather extensive gypsum deposits in the lower part of the St. Louis limestone.; Indiana Department of Conservation

The contribution of mining used to be seen essentially through taxes and royalties; it tends to be viewed now in a more integrated manner. This report, the result of a 2-year research project, attempts to improve that information and to structure the debate around the long term economic impact of industrial mining. The objectives of this research were to assess the fiscal and non-fiscal contribution of mining to Madagascar economy, and by so doing to reinforce the capacities of main stakeholders to prepare for the related challenges and opportunities. Its scope was deliberately focused on large-scale mining, excluding i) mining exploration; ii) artisanal and small-scale mining; and iii) quarrying. This explains why the reader may notice important differences between historical data and information published by EITI in Madagascar, which also includes petroleum exploration activities. The research focused on economic spillovers as a first step. Admittedly, additional research on the environmental and social impacts of industrial mining over time should complement this work to provide for a more complete picture of the contribution of the sector towards sustainable development.

Indiana Geological Survey Bulletin 46; The title of this report as first proposed was "What a Consulting Geologist Should Know About Industrial Limestone" because this effort was born of a request from the Indiana-Kentucky Geological Society, Inc., for a refresher course in the economic geology of limestone. The present title was adopted, however, because the completed report is understandable to anyone with some formal or informal geologic training and an interest in the applied geology of industrial limestones. Many of Indiana's mineral producers have developed a keen understanding of the geology associated with the particular deposit that they work, but because of a lack of training, they do not know how geology can be used in a broader sense to explore and exploit limestone deposits. We believe that this report will help answer some of the questions frequently asked by both the consulting geologist and the mineral producer. Consulting geologists and mineral producers certainly need to know something about industrial limestone. The total tonnage of carbonate rocks mined or consumed in the United States in 1968 was about 603 million tons and the total value about 857 million dollars (U.S. Bureau of Mines, Minerals Yearbook, 1968). To meet the need for this basic building block of our society...

This study builds on a previous study from the raw materials group, a Sweden-based minerals consultancy, originally commissioned by the World Bank in 2008. The trend toward more state engagement in the mining industry as noted in the 2008 study has continued, based on more recent developments. This study includes an expanded section on the new forms of state control which are found in Africa and also in Russia, China, India, and other emerging economies. It lays out the possible political implications of these trends and draws lessons from previous periods of increasing state ownership, including how to avoid previous mistakes. Various metals and the history of nationalization in a number of countries are analyzed as are the possible factors influencing the decision to nationalize, such as the sector's strategic importance and the need to control it. China's role in investing in Africa is discussed noting the issues concerning negotiation strategies, looking at the history of deals made in Sub-Saharan Africa. State ownership is defined in detail in appendix one of this document. A consolidated list of state ownership in mining of selected minerals and mineral refining on which the study is based is presented in appendix two.

The study 'Mining as a source of economic growth in Kyrgyzstan' is developed by the project implementation unit of the World Bank for 'building capacity in governance and revenues streams management for mining and natural resources'. This study is aimed at defining a role for the mining industry in the country and evaluating its possible impacts on economic development in the future. Mineral resources development is an essential condition for successful economic development of Kyrgyz Republic. In fact, it is the only possible way to raise social welfare in remote high mountainous regions. At the present time, some recovery of investment activities in mining industry has been observed. However, the lack of long-term capital investments in mining and geological exploration projects is still acutely felt. International experts have noted more than once that in spite of the significant size of territory and good level of geological study, the minerals potential of the country remains underdeveloped. At present...

This study examines the mining sector's potential to contribute to economic growth with governance in the Democratic Republic of Congo. In the past, mining has been the main engine of the Congo economy. But the revenues and other benefit streams generated by the sector over the years have not been used in a wise or sustainable fashion, largely due to key problems with sector governance. During the past ten years of civil war and conflict, flagship industrial mining declined substantially, and informal and artisanal mining expanded significantly. Now that peace has returned to most of the country and a new democratically elected Government is in place, the potential for the mining sector to contribute to economic growth is excellent. However, achieving growth with governance depends on three principal internal and external factors. The first of these, international commodity prices, is largely out of the Government's control. The second factor, political stability, is clearly critical to growth of the sector; however...

This report firstly presents an analysis of the Nigerian economy as the environment within which the solid minerals sector is situated. It discusses the economy in terms of its distinguishing characteristics, structure and related issues, such that the place of the sold minerals sector can be appreciated. An examination of policy issues and economic reforms to aid the development process is also presented. This study, carried out between February and April 2007, specifically addresses the prospects of developing an industrial mining sector in Nigeria. The current mining sector is dominated by small-scale operations, working below their full potential and literally scratching the surface. Preliminary investigations indicated a lack of up to date information on deposits and lack of microeconomic information on the feasibility of extraction. The study is considered to be important from two different perspectives. First, solid mineral resources are economically, socially and environmentally crucial for Nigeria. There are key knowledge gaps in the sector. In addition the utilization of solid mineral resources is well aligned with the Bank's country partnership strategy...

O conhecimento das propriedades físico-químicas da composição mineralógica dos agregados é de extrema importância para o não comprometimento da obra em que serão empregados. Desse modo, o conhecimento da petrografia, mineralogia e geologia das rochas-fonte para brita também são extremamente necessárias. O principal objetivo deste trabalho foi gerar informações sobre a geologia, mercado produtor e petrografia das rochas-fonte da pedra britada nas principais regiões produtoras do país. As informações disponíveis neste segmento da mineração são escassas, principalmente devido às próprias características do setor onde os investimentos em pesquisas geológicas geralmente são escassas e por vezes pouco exigidas. Os cinco principais pólos produtores de pedra britada, alvos de estudo deste trabalho, incluem as cinco maiores regiões metropolitanas do país: São Paulo,Minas Gerais, Rio de Janeiro , Paraná , Rio Grande do Sul. São locais que possuem diferentes rochas-fonte de brita para cada centro produtor, devido à diversidade geológica e abundância daquelas nestes centros. Assim sendo, na região de São Paulo capital a principal rocha-fonte utilizada são granitos e gnaisses provenientes do Embasamento; na região de Belo Horizonte são os calcários provenientes do Grupo Bambuí; na região do Rio de Janeiro capital são os sienitos alcalinos...

South Africa has a variety of mineral resources, and several minerals beneficiation plants are currently in operation. These plants must be operated effectively to ensure that the end-users of its products remain internationally competitive. To achieve this objective, plants need a sustainable continuous improvement programme. Several frameworks for continuous improvement are used, with variable success rates, in beneficiation plants around the world. However, none of these models specifically addresses continuous improvement from a minerals-processing point of view. The objective of this research study was to determine which factors are important for a continuous improvement model at a minerals beneficiation plant, and to propose a new model using lean manufacturing, six sigma, and the theory of constraints. A survey indicated that managers in the industry prefer a model that combines various continuous improvement models.

El trabajo aborda la dimensión histórica del espacio económico y social del distrito minero Tlalpujahua y El Oro desde la perspectiva del patrimonio industrial. La exploración en busca de minerales preciosos y la explotación de los mismos a lo largo de los siglos xvi al xx, articuló una cultura del trabajo asalariado y facilitó la circulación de nuevos conocimientos, experiencias técnicas y un imponente proceso de innovación tecnológica hacia finales del siglo xix y comienzos del xx. con el agotamiento de los recursos de oro y plata a mediados del siglo xx, el entramado sociotécnico desaparece no así la memoria y los vestigios industriales que dan cuenta de procesos históricos de larga duración, lo cual permite reconocer los cambios habidos en las relaciones sociales de distintos grupos humanos de nacionalidad y condición social diferente —trabajadores, empresarios, comerciantes, etcétera—, que se desplazaron a los minerales con el fin de mejorar sus expectativas de vida. el estudio y puesta en valor de esa experiencia histórico-cultural asegura su resguardo y permanencia como parte del patrimonio industrial de los mexicanos.; This paper deals with the historical dimension of the economic and social space of Tlalpujahua and El Oro Mining District from the perspective of the Industrial Heritage.
