The Electrowinning of Copper from Roasted Sulphides [PDF]
A hydrometallurgical process for the recovery of copper from flotation concentrates has long been considered an attractive possibility. The object of such a method is to produce electrolytic copper without resorting to expensive matte smelting and ...

Integration of physical operations in the hydrometallurgical processing of spent Zn-MnO2 batteries [PDF]
The recycling of spent Zn-MnO2 batteries by hydrometallurgy involves the leaching of material previously treated by physical processing to allow the liberation of electrode particles and the separation of unwanted scrap. The integration of these physical
