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.
A total 200,000t of copper was mined from the pit in 2012. The copper mining complex includes a concentrator facility with ore milling capacity of 120,000tpd and a solvent extraction and electro winning (SXEW) facility. Grasberg mine in the Papua province of Indonesia ranks as the worlds tenth largest copper mine by
Copper ore is defined as copper mineralization that can be mined at a profit. With extremely efficient extraction and processing technologies, material grading as low as .20% copper can be mined economically. Copper sulphide ores in Canada are also a source of significant quantities of gold, silver, nickel, molybdenum, selenium and tellurium
The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the world's total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The U.S. makes the cut, as well, with two mines among the top 20.
Four Big Mines Dominate Zambia's Copper Production
F our big mines dominate Zambias copper production, complemented by several smaller players who also play an important role. All the mines are backed by a wide range of respected international investors. The Zambian government, through its investment holding company ZCCM IH, is a minority shareholder in nearly all of them and is, in effect, the biggest shareholder in Zambias mining
