Lower copper concentrate grades increase slag-forming impurities (Fe, SiO 2, Al 2 O 3), leading to the downward trend shown in Figure 2. Gold and silver recoveries also inversely correlate with the slag amount, and hence with the copper concentrate grade in the feed, but they are largely independent of their own concentrations . The difference ...
In the hydrometallurgical processes, the ore or concentrate is brought into close contact with a leach solution (frequently sulfuric acid) that dissolves the copper and leaves a residue of gangue (and frequently precious metals).
Copper production begins with the extraction of copper-bearing ores in mining or recycling of scrap metal. The ores are processed into copper concentrate, which can be further treated onsite or sold to a smelter. The figures below represent global production and trade of copper contained within ores and concentrates (ICSG, 2015).

only 1.25 moles of oxygen per mole of copper and produces no net sulfate, as follows: 4CuFeS 2 + 5O 2 + 4H 2 SO 4 = 4Cu2+ + 4SO 4 &Q + 8S0 + 2Fe 2 O 3 + 4H 2 O For a copper concentrate containing 30 percent copper as Table 1 — Summary of current processing operations to treat Morenci ore (2017 basis, approximate values only, which may vary ...
In some cases, the concentrate is submitted to an additional processing step to extract a by-product (e.g. molybdenum sulfide). Finally, the copper concentrate is dried ready for transportation to the next step (smelting). The copper concentrate production process does not involve any chemical modification of the original ore body. 2.
MG14 and Cattle Grid South is currently planned to be sold as a concentrate. Alternatively, this product can be further refined via a hydrometallurgical process to create copper metal. Stage 4(A): Selling as a concentrate. Selling as a Concentrate: At this stage, the copper concentrate, typically containing 20–25% copper, can be sold to ...
an excellent process for smelting fine concentrate from flotation. It is a fossil fuel fired hearth furnace for smelting concentrate and producing copper matte. The reverbs began to decline in …
In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia []) owing to the exhaustion of rich copper resources.The flowsheet of processing copper ores is developed for each particular ore, but there are some …
The Production Process of Copper Cathode and Concentrate. But the copper concentrate is a product of an earlier stage of the production process: Mining: Copper ore is extracted from the ground. Crushing and Grinding: The ore is first crushed and then fine ground into exceedingly small particles.
A copper concentrator is milling 15,000 tons/day of a chalcopyrite ore assaying 1.15% copper. The concentrate and tailings produced average 32.7% and 0.18% copper, respectively. I let you do the math! Three product (bi-metallic) formulas

Freeport Indonesia Smelter is designed to have the largest copper concentrate processing capacity in the world. The results of this smelter processing will be ...
Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. … See more
With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing the increased amounts of …
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.
This circuit produces a high grade concentrate assaying approximately 16% copper, and a low grade concentrate assaying approximately 2.5% copper. The high grade concentrate is thickened and filtered in the high grade oxide copper thickeners at the concentrator plant prior to transfer to the leach plant for electrowinning of copper in the leach ...
Copper concentrate is a product made by processing/enriching copper ore, which usually has a relatively low metal content and is not suitable for direct metallurgical processing. Usually, copper content in concentrate varies from percentages in the teens to several tens of percent, which enables further processing in copper smelters and ...
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.
The purpose of smelting is to enrich most of the copper in the copper concentrate in the matte phase. The gangue, oxides and impurity elements were combined in the slag phase to completely separate the copper matte in the slag phase. In this paper, a mathematical model based on the optimization of copper concentrate cost and the content of impurity elements in …

The smelter is basically a large furnace which melts the concentrate and drives off the sulfide to leave molten copper metal this is still contains impurities and it needs to be refined further to make it a salable product. Returning to the overall process; that is the process for the sulfide ores and the oxide ore as I said are treated ...
Copper concentrate. Copper concentrate is a crucial intermediary product in the copper production process, valued for its high copper content and economic significance across industries such as electronics, construction, and renewable energy.
The first phase, mineral processing, is to release the copper minerals and remove waste elements, such as alumina, limestone, pyrite, and silica, in order to concentrate the copper minerals and other nonferrous minerals of value into a product containing between 20 and 30 percent copper.

Copper concentrate (CuFeS 2) is fed into the furnace along with a flux of silica sand, SiO 2, and oxygen, O 2. The flux is used to control the chemistry of the slag. In particular, it causes the iron (Fe) in the copper concentrate to accumulate in the slag phase, while the copper (Cu), accumulates in the matte phase. Copper Concentrate
