The mine produces over 1.1 million tonnes of copper ore and in excess of 185,000 tonnes of copper concentrate per annum. The concentrate contains approximately 29 copper and is exported to.Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2 ). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore.This means that 95.7 of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The Cu Loss can be calculated by subtracting the Cu Recovery from 100 Cu Loss = 100 – 95.7 = 4.3 This means that 4.3 of the copper present in the ore.
Cupellation is a process where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like led, copper, zinc, and others present in the ore or alloyed metal.Copper's recycling value is so great that premium grade scrap normally has at least 95 of the value of the primary metal from newly mined ore.
