Despite a record of mineral activity that dates back to Biblical times and the occurrence of a wide variety of minerals, as well as continuing efforts to discover major ore deposits, Ethiopia's mineral resources ahve remained of minor importance in the world economy.
Sources. Copper is a common element in many minerals and sometimes occurs in pure, native form. Most of the world's copper comes from the minerals chalcopyrite and chalcocite. Chrysocolla and malachite also are mined for copper. Other copperbearing minerals include atacamite, azurite, bornite, brochantite, cuprite (copper oxide), dioptase,...
MINING HISTORY OF THE COPPER BASIN. During the early mining days, mules pulled ore cars underground. Some mules, upon entering the mines, never again saw the light of day and hence became blind. Both mules and oxen powered a whim (the wheel where rope was wound) which turned and brought the ore to the surface.
Dec 16, 2011· Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits.
