Hydrometallurgical Processing - ScienceDirect

2014-1-1  Copper processing involves two common flow sheets shown schematically in Figure 2.7.4 . The flow sheet that is typically employed at a mine site is the hydrometallurgical process that treats solution from heap leaching by SX and electrowinning. Between 20% and 30% of the world’s refined copper is produced by hydrometallurgical methods . The pyrometallurgical flow sheet, which produces

Hydrometallurgical Processing - an overview ...

A combination of pyrometallurgical and hydrometallurgical processing is required to obtain pure PGM from natural deposits or slimes obtained from copper or nickel processing. When PGM are produced as a by-product of copper or nickel operations they are extracted from the electrolytic slimes using a succession of chemical procedures and precipitation techniques to effect separation of the impure
