Copper Mining and Processing: Processing of Copper Ores. Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % 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 .

So far, researches about the combined collector for copper oxide ores have been mainly based on two kinds of anionic collectors, namely hydroxamate and xanthate [22,23]. However, studies about the anion and cation collectors used as combined collectors for sulphidizing flotation of copper oxide .
copper close to the surface. The sulfide and oxide ore will be mined through conventional open pit mining techniques. Concentrate ore (mostly comprised of sulfide ore) will be processed by crushing, grinding, and floatation to produce copper concentrate product, which contains copper, silver, and possibly small amount of gold, and molybdenum.
Sulfide ores are used to produce a matte (40 – 50 wt % Cu) and a disposal slag (ca. wt % Cu). In contrast, oxide ores are processed directly to impure black copper ( 95 wt % Cu) and to a copperrich slag. The two ore types can be smelted together to produce matte and a slag with low copper content.

flotation tests were unsuccessful in terms of both recovery and grade of concentrate product. The highest copper recovery of concentrate was found as % with % copper content. The concentrate with highest copper grade of % was obtained with only % copper recovery. Unsuccessful flotation of the test
Mixed ore from the KOV OP is transported by truck and stockpiled near the oxide crushing area. It is blended before being crushed by jaw crushers and conveyed to stockpiles in the milling section. Milled mixed ore is processed in the flotation circuit to produce a final sulphide concentrate, a final oxide concentrate, and a tailings stream.

The primary lead production process consists of four steps: sintering, smelting, drossing and pyrometallurgical refining. To begin, a feedstock comprising mainly of lead concentrate in the form of lead sulphide is fed into a sintering machine.
A slurry of mixed copper oxide product was generated, and downstream testing on product quality carried out. The pilot programme successfully demonstrated 95%+ copper recovery from the concentrate, and generated a 40%+ Cu product.
