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 copper is present principally as chalcopyrite in extremely close association with both the sphalerite and pyrite. We have all the laboratory and plant equipment you need to test or build/operate your plant. We can IMPROVE ALL PLANTS / Mineral Processing Engineering & LABORATORY Ore Testing. 911Metallurgy Engineering.
Additions of chloride ion (Cl-) are also known to enhance chalcopyrite leaching, although a review of the literature on chalcopyrite leaching reveals some controversy over the actual effect of chloride and the conditions under which it is effective. Dutrizac and MacDonald studied chalcopyrite leaching using 0.1MFe2(SO4)3-0.1MH2SO4 (sulfuric acid).
It has been reported that chalcopyrite can be floated selectively from an ore containing pyrite, sphalerite, and silicious gangue minerals without using a collector. Sodium sulfide was used as a promoter, presumably to clean the chalcopyrite surface of its hydrophilic oxidation products. Later it was found that the potential of the pulp, measured with a platinum-calomel electrode pair, was
Leaching Chalcopyrite is the holy grail for hydrometallurgists (Leachers), difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow. Having said that, it is not 100% not leachable, not unusual for ore dumps (low grade) containing chalcopyrite to be placed under leach but report low recovery +/-30% TCu over several years and the rate is around 0.5-1% per month
2.2. Chalcopyrite Ore Processing The first step in the chalcopyrite processing is to liberate the copper minerals and remove waste constituents such as alumina, limestone, pyrite and silica so that the copper and non-ferrous mineral values are concentrated

The pyrite processing mostly in flotation, flowed by the gravity separation process, and gravity-flotation combination. Gravity separation process For ore with simple ore properties, coarser stone size or uneven stone size, a single gravity separation process can be used.
The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite-copper, you need to bring the plant’s pH up to the other side (right side) of the PYRITE curve. The more flotation collector you have on, the higher you will need to increase that pH for effective pyrite depression. You also need to insure your pyrite

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.
