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

The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper.

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

Crushed rock is then loaded on to a conveyor belt which takes it to the concentrator. In the concentrator, primary SAG mill (We do not manufacture) and secondary ball mills grind the rock until it is a fine powder, Then the copper rock is crushed and screened, with the fine sulfide rock going to froth flotation cells for recovery of copper.

A-Z Guide to Screening Ore, Rock & Aggregate. A simple definition of a “screen” is a machine with surface(s) used to classify materials by size. Screening is defined as “The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface”.

It will be crushed and then screened at the secondary crushing circuit. The screened ore is sent to the milling circuit where it will undergo regrinding. The final slurry will be sent to the flotation circuit that comprises scavengers, roughers, cleaners, and recleaner circuits to produce copper concentrate with a grade of 22% Cu.

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.
