Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity ...
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
Concentrate production is a process where the main metallic compounds of the mines ore are separated and concentrated. This concentrated material is then sold to smelters for further refining. The marketing of base metal concentrates is a key element of Tecks business.
