Ore Deposit an overview ScienceDirect Topics

Ore deposits are rarely comprised of orebearing minerals, but usually associated with RFM during mineralization process. These associated minerals or rocks, having no significant or least commercial value, are called "gangue" minerals. Pure chalcopyrite having 34.5% Cu metal in copper deposit and sphalerite with 67% Zn metal in zinc deposit are hosted by quartzite/micaschist and
