sulfuric acid copper leaching

A statistical approach to the experimental design of the

Sulfuric acid leaching did not provide more than 76% copper extraction because the only slightly native copper that was leached (23%) For this reason the sulfuric acid leach residue still had 030% native copper and 052% total copper
