Metalcess offers
comprehensive solution for your copper metallurgy project, varying from copper
ore, copper scrap, WEEE, copper slag/dross or leaching residue, etc. From
process design, detail engineering and equipment supply of the production line,
Metalcess provides not only customer-tailed technology but also responsive
service. Metalcess makes it possible for our customer to have different final
products like copper cathode and copper sulphate, as well as such byproducts as
sulfuric acid, precious metal.
