Copper Ore Types Sulfides vs. Oxides. Copper containing rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue. There are two main copper ore types of interest copper oxide ores and copper sulfide ores. Both ore types can be economically mined,
Namibian Mining Town. Tsumeb belongs like Grootfontein and Otavi to the so called Otavi, Maize or Copper Triangle and lies in a region that receives exceptionally high annual rainfalls compared to the rest of the country (more than 550 ml annually), which allows intensive agriculture. Neither corn and grain nor fruit and vegetables underline
Copper Applications in Metallurgy of Copper amp; Copper Alloys. Such ores are called porphyries. Where mineralized rocks become outcropped or shattered, the sulfide minerals undergo chemical changes due to air, groundwater and heat, giving rise to the other main variety of copper minerals the oxidized ores.
mined copper ores in the Windhoek area, but it was not until the turn of the century that major mining started, for copper ore, at Tsumeb by a German company2. Namibia was allotted to Germany at the Berlin Conference in 1884 on the basis of dubious treaties obtained by Adolf Luderitz, a prospector/explorer, from the local leaders.
In mineral rich Namibia, some 10 groups can be found with some 105 species described on this web site. The now closed Tsumeb Mine is known worldwide to mineral collectors and mineralogists. Gemstones tend to be the most desirable, especially diamonds in Namibia and the connection and history with the Sperrgebeit and Kolmanskop.
Copper is one of the world's most important industrial minerals, and Africa is an important world producer. While output is traditionally dominated by Zambia, South Africa and Katanga Province in the south of the Democratic Republic of the Congo, many African nations contribute to copper production, and many African nations have undeveloped ore resources.

Massive sulfide Cu Zn( Ag Au) deposits are sporadically developed along the 350 km strike length of the late Proterozoic Matchless amphibolite belt in the Damara orogen in central Namibia. The amphibolites represent metamorphosed tholeiitic basaltic rocks formed in an extensional tectonic setting.
The Haib is one of the largest undeveloped copper resources in Africa. The deposit is located in extreme southern Namibia, about 9 km from the Orange River (boundary with South Africa). The location is in rugged terrain just east of the main (sealed) highway that connects Cape Town, South Africa and Windhoek, Namibia.
Sulphuric acid is a critical component in the mining industry particularly for uranium and copper production businesses. Thus, the smelter can take a by product of copper and turn it into something of value for Namibia. main ores of copper in namibia Mineral Processing EPC
Copper ores The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or
The Kombat Mine is one of the most significant copper mines in Namibia. It originally commenced mining in 1962 and operated until 2008, producing 12.46 million tonnes of ore
Collectable Copper Ores and Minerals. This is a selection of the most commonly collected copper ores. Also included are a few other interesting ores of metals often alloyed with copper such as zinc, lead and bismuth. Illustrations are being added where available.
Copper mining in Africa predominantly stems from mining projects in the DRC (48 projects), Zambia (34 mining projects) and Namibia (21 projects) with a total of 134 copper mining projects throughout Africa. Due to its excellent conducting properties, coppers pivotal role in electronics manufacturing makes it a continually sought after mineral and a growing commodity throughout Africa.
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using todays compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, its roasted, which helps to convert sulfides to oxides.
