Our copper chloride leaching process utilizes our highly effective atmospheric chloride leaching technology, including gold and silver recovery. We have coupled this with worldrenowned VSF solvent extraction and electrowinning technology to make a process that is especially effective with lowgrade and impure copper feed materials.

Catalytic leaching with ferricyanide to improve silver extraction from Veladero and Pierina goldsilver ore has been investigated through tank leaching and column leaching tests. The results of comparison tests show that improvements of Au and Ag extraction are not significant in catalytic leaching over baseline leaching.
