Copper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

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 refineries.

Copper concentrate is smelted and converted to metallic copper, which allows it to attain forms that can be submitted to further refining, more than 99% pure, as in copper anode and copper blister. The main application of copper anode is to use it as raw material in the process of electrolytic refining, to produce the electrolytic refined cathode, purity 99.99%.

Copper Smelting Process. In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50-percent copper matte. The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at

Copper Concentrate is created by purifying Crushed Copper Ore in one of two different crafting stations. The crafting stations come with different ratios, labor cost and time cost. The process to make Copper Concentrate also gives a byproduct of Wet Tailings which is a pollutant. Copper Concentrate is the last step in the production line for a Copper Bar.

Copper smelters can be classified as integrated or custom. Integrated smelters, as the name suggests, process concentrates from their own mine(s) to anodes and (usually) cathodes. Custom smelters process concentrates from non-related entities (also called custom mines). However, the lines of distinction have become blurred.

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.

Copper concentrates are either smelted and refined in-house, or sold to custom smelters. The concentrate may be smelted to produce blister copper for sale to a custom refinery, or the blister copper may be refined to cathode, which is then sold into the market. Concentrates sales contracts are specialised and very complex.

The blister copper is tapped, further refined in an anode furnace and finally electrolytically refined to pure cathode copper. At Olympic Dam the concentrate is flash-smelted directly to blister copper. In this process copper concentrate is fed into the smelter with oxygen-enriched air.

Copper concentrate quality drivers. CRU data shows that the average copper concentrate grade has declined by 7% since 2007 (from ~27% to ~25% Cu content). The grade of the concentrate is primarily driven by the mineralogy of the copper deposit, as well as the success rate (recovery) of metal during beneficiation.
