Fortunately, a high density of gold allows for effectively separated and concentrated using gravity method with low costs, such as jigs, water gate, shaking tables etc. Where the size of microcrystalline gold ore minerals are below 150 microns to 0.8 microns and fatherly look of metal ore we need a tool microscope.
We are trying to process gold from arsenopyrite and chalcopyrite ore. Our XRF indicated that there was a high concentration of gold along with a variety of minerals. We have tried various methods of refining without much luck, due to all of the other minerals with different melting points. We had a fire assay done .
Carbon in Leach process is widely used in the mining industry and in particular, it is an integral step of gold processing in gold extraction. Normally the CIL process can concentrate gold from 2.53.5 g/t in ore to 2000 to 6000 g/t on carbon.
Application of geometallurgical modelling to mine planning in a copper gold mining operation for improving ore quality and mineral processing efficiency by C. Beaumont1and C. Musingwini2 amp;38,272 Kansanshi mine, located in northwestern Zambia, uses conventional open pit mining to produce primarily copper, with gold as a by product.
With ores of higher gold content , cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low grade ores, heap leaching is practiced.
The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic gold, principally in arsenopyrite and pyrite, is also important.
