Abstract
A novel process for enhancing the leaching rate of a mineral wherein the mineral is characterized by the tendency to form a reaction product layer during leaching. A suitable particulate modifier such as carbon is mixed with the mineral prior to leaching and selectively alters the characteristics of the reaction product layer. The process is particularly useful for leaching chalcopyrite, sphalerite and galena.
