In addition to processing copper ores, new and old copper scrap or copper alloys can be melted, re-purified, and recycled into new components. It is estimated that such recycling supplies 50% of copper used in the copper industry (Scott, 2011). In 2010, 770,000 metric tons of copper were recycled, at an estimated value of nearly six billion dollars (Papp, 2010).

Copper Mining and Processing: Processing Copper Ores. 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

First application of the thin-layer process on copper sulfide ores (chalcocite) contains about 1% Cu. In 1994, the design capacity was of 75,000 tons/year which was increased to 80,000 tons/year subsequently. Process modifications included irrigation using preheated raffinate solutions, use of semiburied drippers, bottom aeration, and “grasshopper” type stacking. “On and off” reusable

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.

The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.

Nearly all copper ores of the sulfide type such as chalcocite, chalcopyrite, and covellite are treated through the well-known process of smelting. After the ore is crushed to powder, it is treated with froth flotation, whereby the powder reacts with reagents that treat the copper to make it hydrophobic. After being treated further with water and a ing agent, frothing is enhanced.
