Still, it is mind boggling enough to think about how much dirt has to be dug out , crushed, milled, refined to produce every single gram of gold these days.
Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining.
Our processing experience includes crushing circuits, ore stockpiling and reclaim systems, pre-concentration, milling circuits, flotation plants, solids . For 30 years we have grown our knowledge in the gold mining industry and, as a result, we are able to meet the design requirements of gold mines and gold plants, for any.
