  • Copper Extraction And Production Institute Of Rare

    copper extraction and production. copper occurs in natural ore deposits around the world. here we explain the ore-bearing rock production path to the final product, which is the highest pure trading metal available and used in a variety of applications essential to modern life.prior to the development of the solvent process in 1959 the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect traded for iron by contacting the copper-bearing solution with scrap iron.
