Madziwa Copper Mine Near Shamva, Zimbabwe | The

The Madziwa Copper Mine is near Shamva, Zimbabwe. The site was first discovered in 1958. The ore mined is composed of polydymite, chalcopyrite and pentlandite with waste material consisting primarily of chlorite. The ore body is described as tabular shaped of unknown dimensions. The mineralization at this location is from the Neoproterozoic era ...

Ore Deposit - an overview | ScienceDirect Topics

Ore deposits are rarely comprised of 100% ore-bearing minerals, but are usually associated with rock-forming minerals during the mineralization process. These associated minerals or rocks, having no significant or low 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 ...
