For this study Methanesulfonic acid (MSA) and hydrogen peroxide (H2O2) were used to leach chalcopyrite. Tests were conducted at temperatures ranging from 22-85°C and at MSA concentrations ranging from 50g/L to 100g/L MSA. A copper recovery of 94% was obtained using a solution containing 75g/L MSA and 3% H2O2 conducted at 65°C. Arrhenius evaluation of the experimental results found that at 75g/L MSA the reaction is a mixed controlled mechanism and that at 100g/L MSA the reaction is diffusion controlled.Type
