Hydrometallurgical Copper Extraction Process

15.12.2018  Simply stated, copper concentrates are dissolved in a ferric chloride-copper chloride solution in two stages of leaching. The pregnant solution from the first leach is high in. cuprous ion concentration. This solution is cooled and cuprous chloride crystals are precipitated. These crystals are washed, dried and fed to a fluidized bed where hydrogen reduction takes place,
