112 Extraction of Nickel and Cobalt from Sulphide Ores Sulphide ores were mostly created by i the intrusion of molten magma from the mantle into the crust of the earth and ii the formation of localized metalrich sulphide ore bodies by sequential solidification andor hydrothermal leaching and precipitation

Copper Sulfide Flotation Circuit These large scale milling operations handling low grade ore must provide very careful planning in the design of their plant flowsheet and selection of equipment Milling circuits must be as simple as possible and for large tonnages as few as possible Summary of Porphyry Copper Sulfide Processing

The principal difference between the highgrade ore A and ore B was the arsenopyrite and pyrite contents Ore A contained approximately 61 pct arsenopyrite and 9 pct pyrite and ore B contained 35 pct arsenopyrite and 24 pct pyrite The lowgrade ore contained only 1 pct arse­ nopyrite and 5 pct pyrite

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different

In many locations where they had initially been recovering 90 of the assay values processing oxidized surface ore with the rebellious sulfide ores they were recovering less than 50 The rest of the precious metals in their ore simply flowed uselessly out from the mill and into the tailings pond

Bioleaching is a promising and sustainable technology that is ecofriendly has a low cost has low energy consumption and is simple At present bioleaching is not limited to highgrade sulfide minerals instead it is widely used in metal recovery from solid waste such as Ewaste sludge sediment batteries catalysts and lowgrade ore
