8.2 Mining and Ore Processing – Environmental Geology
But separation of ore minerals is only the preliminary stage of metal refinement, for most metals the second stage involves separating the actual elements within the ore minerals. For example, the most common ore of copper is chalcopyrite (CuFeS 2). The copper must be separated from the iron and sulphur to make copper metal and that involves ...
Physical Processing: Innovations in Mineral Processing
The characterization of these ores is challenging due to low gold ore grades, presence of variable proportion of preg-robbing total carbonaceous matters (TCM) with sulfide inclusions, visible and invisible gold in different sulfides phases (e.g., pyrite, chalcopyrite, chalcocite, and bornite) and also in iron oxide phases (e.g., magnetite ...
