9 Ore Deposits and Economic Minerals – Mineralogy
An ore deposit is a mineral deposit that can be produced to make a profit Thus, all ore deposits are mineral deposits, but the reverse is not true Many factors control the profitability of an ore deposit We call the amount of known ore in a deposit the reserves Ore deposits formed by lateral secretion are formed by metamorphic reactions during shearing , which liberate mineral constituents such as quartz, sulfides, gold, carbonates (PDF) ORE DEPOSITS (Ore Geology) ResearchGate Natural concentration of an ore mineral in a massive rock body is defined as an ore deposit It may be of any shape and form but its size is of real importance A small patch or layer of bauxite, say one meter thick and a kilometer long will not make an ore depositMineral Ore Deposits: Meaning, Origin and Types

Ore deposits formed by lateral secretion are formed by metamorphic reactions during shearing , which liberate mineral constituents such as quartz, sulfides, gold, carbonates and oxides from The placer deposits usually form from primary deposits in which the ore mineral is widely disseminated and uneconomic Concentration occurs when the surrounding rock is eroded away and the heavy ore mineral becomes concentrated by erosional processes During transport of this material, concentration can occur within depressions, such as where a Geological ore deposits The Australian Museum metalliferous products The microscopic investigation of these ore minerals is thus of high priority for anybody involved in the prospecting of oremineral deposits, the extraction of these minerals (ie, the mining industry), in their refractory and metallurgical treatment, and for those responsible for the final products From 1920 oreORE MINERALOGY EOLSS

A mineral is a naturally occurring crystalline solid that cannot be physically broken down into smaller components Deposits of minerals form when a medium that contains and transports mineralmaking ore releases and deposits the ore Magma is one such medium that transports ores When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in the newly Mineral exploration is the process by which mineral resources essential to society are discovered and is the initial wealthcreating part of the mining value chain (Porter, 1985)In the past a prospector with a good eye identified an area of anomalous metal concentration or altered outcrops, which occasionally led to discovery of an ore depositMineral Exploration: Discovering and Defining Ore Ore Deposits Western Kentucky Fluorspar District The IllinoisKentucky Fluorspar District is located in Hardin and Pope Counties in southeastern Illinois and in adjacent Crittenden, Livingston, and Caldwell Counties of western Kentucky, within the Paducah 30 x 60 minute quadrangleOre Deposits, Kentucky Geological Survey, University

An understanding of the basic geologic characteristics of mineral deposits is crucial to evaluating known deposits and delineating prospective areas of mineralization Studies on mineralogy, framework geology, geochronology, and ore deposit genesis can help to better define the characteristics of mineral deposits and can lead to new discoveries of minerals The purpose of this special issue is to publish highquality research papers as well as review articles that seek to address recent advances on hydrothermal processes and metal mineral ore deposits Particular interest will be given to papers exploring or discussing metal solubility, speciation, migration, and precipitation in hydrothermal fluidsFluids, Metals, and Mineral/Ore Deposits Hindawi 4 Identifying the equilibrium mineral assemblages, which in turn are necessary for understanding phase relations and the correct interpretation of geothermometric results Textures of economic ore deposits I Magmatic ores: 1 Cumulus textures: result from the settling of an ore deposit from a crystallizing magmaTextures of Ore Deposits BU
