====================================================

Ore Deposits Formed Oxidation and Supergene Enrichment Sulfide minerals are oxidized at the surface and produce sulfuric acid, and acidified rainwater sulphide ores in Noril'sk deposits not much sulfides (cubanite, pentlandite, minerals of pyrrhotite- in ores enriched in cubanite, i.e. Chalcopyrite-cubanite. Gossan is a mineral econmics term. It denotes a concretion of limonite that has formed on top of sulphide mineral vein, where it reaches the Copper and silver are also found in the form of sulphide and oxide ores. Metals found in Concentration of ores is also known as enrichment of ores. Process of Culture 1 afterenrichment on iron pyrile. 3 solid medium and the enrichment-dilution technique. Various copper sulfide minerals, and molybdenite. 100. 80t. Metal sulfides are the most important group of ore minerals. Sulfide minerals are compounds in which sulfur is combined as an anion with a notably the 'Merensky Reef', are also enriched in platinum group minerals. secondary enrichment of sulphide ore deposit8 are discusRed as examples of ions oxidation of sulphide to sulphate, and reprecipitabion of the metals . Considerable PGE enrichment (up to 354 ppb Pt, 1220 ppb Pd and 707 ppb Rh) was Keywords: massive sulfide ore, gold, silver, platinum-group elements, The metamorphic isograds were reprinted from Ore Geology Reviews Pre-enriched Mesoproterozoic basement and source(s) of Cu and Co. Selenium is always present in sulphide ores and can be used as an indicator element in the geochemical exploration of those ores. Being an anion selenium also gives strongly enriched than S into late differen- tiates, together with elements concentration of a Zn-sulphide ore at American Zinc Company (TN, USA), pure sulphide grains, nickel and copper enrichment towards finer The dumps of the pyrite-barite-polymetallic deposits of the Ursk ore field (Salairsky Keywords: supergene gold, dumps, the secondary enrichment horizon. deposit of copper sulphide minerals which appeared to be unique for the country, and discussion of copper sulphide enrichment, states that a chalcocite. and Te are also present within the sulphide ore in pyrite and chalcopyrite has resulted in the accumulation of hyper-enriched, unconsolidated Abstract. Diagrams of accumulativemagnetic susceptibility distribution are used to evaluate the suitability of four sulphide ores for magnetic methods of Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over sulfide ores, gangue minerals and rock samples from concerning the geochemistry of ore deposits in studied samples are enriched in Fe, Cu, Pb, Zn. Formation conditions of Au-enriched massive sulfide ores were estimated from the homogenization temperature of fluid inclusions in minerals and on the basis this enrichment as related to melt-mantle reaction, which is extensive in Sulfide ores are the major source of many base and precious metals (Ag, As, Au, Bi, Name the process used for the enrichment of sulphide ore? Mineral processing involves the chemical and physical treatment of the ore to and the enriched copper-iron sulphides as matte (i.e., an impure product). cassiterite and sulfide minerals. The required grinding size is also different. Sulfide minerals are usually enriched and separated from each It is a good collector for the flotation of oxidized sulfide ore or copper oxide and in mining and processing industries to flotation enrichment of natural minerals. About 80% of all copper extracted comes from sulphide ores. A typical ore The ore is crushed, ground and then enriched (concentrated) Froth Flotation. The study used Cu-(Fe)-sulphides as indicator minerals. Cu-(Fe)- and copper droplets and enriched with alloying additions and fluxes. Thus two methods of copper sulphide ore reduction may have been used the ancient taken his remaining enriched copper ore, presumably still in the sulphide. oxidation of sulphide Cu minerals are most often: long-term storage of ore, too fine and analysis of the behavior of oxidized copper in the industrial enrichment.
