Mining chalcopyrite is a complex process that involves crushing the ore, followed by a series of physical and chemical treatments to separate the copper from other minerals and impurities. The most common method of copper extraction from chalcopyrite is pyrometallurgical processing, which includes smelting and refining.

Albion Process™ has real-world success in delivering consistently high recoveries – up to 97% in refractory gold and over 99% in chalcopyrite copper concentrates. It has much lower capital cost than traditional leaching plants like pressure oxidation (POx) plants and because it operates at atmospheric pressure, it completely avoids the ...
Chalcopyrite is a mineral and ore of copper. Its chemical composition is CuFeS2, meaning it contains copper (Cu), iron (Fe), and sulfur (S). Chalcopyrite is one of the most …
The bioleachings of chalcopyrite ore were compared after inoculating different cultures enriched from the original acid mine drainage sample. The results showed that the higher bioleaching performance was achieved for inoculation with the enrichment D (0.5 % S, 2 % iron and 1 % chalcopyrite) compared to other enrichment systems.

Chalcopyrite is the main mineral source of copper ore for extracting and producing copper. However, with the continuous mining of copper ore, the grade of chalcopyrite decreases year by year and its composition becomes more and more complex. The traditional pyrometallurgical extraction process has been unable to make efficient use of such resources, …
