Processing of Complex Materials in the Copper Industry

A global copper mine-by-mine review undertaken by ICSG found that the global average copper ore grade was as low as 0.45% copper in reported reserves and only 0.65% copper in 2015 copper mine production. Global weighted average of copper concentrate output in a large sample of plants was around 25% copper in 2015 data.

Recent Advances in Copper Ore Processing and Extraction

The flotation test results of actual copper sulfide ore showed that pre-magnetized butyl xanthate could increase the copper recovery of copper concentrate by 3.06 percentage points and the sulfur recovery of sulfur concentrate by nearly 3 percentage points, and effectively reduce the mutual content of copper and sulfur concentrates.

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. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Copper Pathways Map

The smelting process involves heating and melting ore to extract metal. Refining refers to any process increasing the grade or purity of the metal. The result of the refining process for copper production is copper cathode, which is generally 99.9 percent pure. The figures below represent global production and trade of refined copper (ICSG, 2015).

Production of copper concentrate from sulfide ores

The production of copper concentrate from sulfide ores is a vital process in the copper mining and metallurgical industry. Copper sulfide ores, which contain significant amounts of copper in the form of minerals such as chalcopyrite, bornite, and chalcocite, undergo a series of physical and chemical treatments to extract and concentrate the copper for further processing.

Copper Concentrate Enrichment Process

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.
