Effect of polyvinyl alcohol on copper leaching from
The new copper-based preservative systems leach a relatively high level of copper and, thus, generate some environmental concerns. Polyvinyl alcohol (PVOH) is known to complex with copper(II) and is water soluble. The effect of co-addition of fully hydrolyzed PVOH on the leaching of copper

Continuous biological leaching of copper from a chalcocite
The copper bioleach rate achieved in the first bioleach stage was 16 mg/L/h for the ore and 250 mg/L/h for the concentrate. This study demonstrated the feasibility of the continuous biological leaching of either a chalcocite ore or a chalcocite concentrate in a 3 g/L chloride environment.
