processing of refractory ores, since the cost of additional processing such as fine grinding or sulphide oxidation is reduced by reducing the mass of material to be treated. In some cases, the grade of gold in the concentrate is sufficiently high to ship directly to a smelter, avoiding all downstream processing costs and greatly
28/01/2016 · THE EFFECT OF GANGUE MINERALOGY ON THE DENSITY SEPARATION OF LOW GRADE NICKEL ORE Density separation is widely used to pre concentrate minerals and reject unwanted gangue. For base metal sulfide ores, dense medium separation(DMS) is used to separate the sulfide minerals, which are relatively dense. After DMS it is treated in Flotation .

goldcontaining copper ores, base metal ores, copper nickel ores, platinum group ores and many other ores where the other processes are not applicable. Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment ( carbon prefloat) for upgrading the lowsulphide and refractory ores for further treatment.
31/08/2020 · The above flowsheet shows a basic copper mine process, from mine to metal. There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary ...
When base metals are produced by pyrometallur gical processes from primary egory source ores, precious metals resulted to be concentrated into the electrolytic refining anode slimes, this situation is mainly because they have a heavy specific gravity and a general stronger affinity to metalsulphide or metal phases than that to oxide phases ...
01/01/2012 · Chalcopyrite Ore Production The sulfide ore minerals including chalcopyrite (CuFeS 2), sphalerite (ZnS), galena (PbS) provide the major sources of the world's base metals (Cu, Zn, Pb, respectively), whereas pyrite is virtually ubiquitous as a metalliferous mineral in sulfide ore deposits (Crang and Vanghan, 1994).The first step in recovering metal from their .
01/01/2005 · Flowsheet selection for freemilling ores can be relatively straightforward, with the key issues revolving around comminution circuit selection, the use of heap leaching, treatment of highsilver ores, and flotation options for freemilling sulfides.
