An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant. It was established that recovery of copper and cobalt from this ore with hydrometallurgical treatment is not economical, so using flotation to increase the concentration of copper and cobalt was chosen. When flotation of the

Frequently, large copper sulfide ore bodies are overlain by mixed copper oxide-copper sulfide ores in which the copper is difficult to recover. Such ores, when heated with a chlorine ion donor such as ferric chloride or cupric chloride to a sufficient temperature in the absence of air, can be converted to copper chlorides which are water soluble and from which the copper can be

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it. To be applicable to this process, the ores must contain copper

A life cycle assessment study was carried out to assess the potential energy and greenhouse gas benefits of a conceptual flowsheet of the rock smelting process, using copper ore as an example. Recovery and utilisation of waste heat in the slag (via dry slag granulation) and offgas streams from the smelting step was also included in the study
