Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Processing Options Selection of the treatment process for porphyry copper-gold ores is based on the nature of the ore and the gold association with the contained minerals. Operating plants ~;uch as Ok Tedi [9] and Freeport [10] use a liune circuit with selective collectors. This choice is based on the presence of variable amounts of pyrite in ...

Copper minerals, even though minor components of precious metal ores, dissolve in these cyanide leaching solutions, consume cyanide, cause fouling of mill solutions, and thus interfere with the precipitation and recovery of gold.2,3,4 Here is a summary of laboratory investigations on the use of cyanide solutions as extractants for copper from ...
Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore ...
It is well known that cyanide soluble copper dissolves in cyanide solutions to form toxic copper-cyanide complexes such as Cu(CN) 2 −, Cu(CN) 3 2 −, Cu(CN) 4 3 −.A number of studies have been published to treat gold-copper ores by either adding ammonia to the conventional cyanidation process, or recycling cyanide after the leaching stage (La Brooy et al., 1991, Muir et al., 1991, Muir et ...

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 …

The treatment of a copper sulphide-bearing gold ore by direct cyanide leaching, ammonia pretreatment and ammoniacal cyanide leaching was investigated. Dissolution behaviour of gold and copper in these leaching systems was demonstrated. Severe interference by the copper containing sulphides with cyanide leaching of gold is observed at ρ(NaCN ...
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin.. These ore bodies range from around 10 million to >4,000 million tonnes of contained ore, and have a grade of between 0.2% and 5% copper, with gold contents ranging from …

Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
The copper-gold ore deposit at Gedabek in western Azerbaijan is described, together with the various processes that are used to extract the gold, silver and copper from these ores. The processes include heap leaching, agitation leaching and flotation. Geometallurgy is used to classify the various types of
