DetailsBoth depressants applied by themselves showed a slight depression of the mineral chalcopyrite and galena. However, the separation was significant using a 200 mg/L 50:1 mixture of SS and CMC, allowing galena to settle without affecting chalcopyrite floatability. An additional dosage of SS and zinc sulfate generated a better separation.

DetailsOccurrence of Chalcopyrite and Useful Mineral Association. Chalcopyrite occurs as a primary mineral in hydrothermal veins, stockworks, disseminations, and massive replacements, or as an ex-solution product in mafic igneous rocks. It can also be found as a sedimentary origin, controlled by redox conditions.
DetailsChalcopyrite is the most wide-spread copper sulfide mineral, but the dissolution of chalcopyrite in acid solution is still refractory by both chemical and biological leaching due to high lattice energy and strong passivation effect (Watling, 2013). As a result, problems including poor leaching rate, long bioleaching routine and low efficiency ...
DetailsAmong them, chalcopyrite (CuFeS 2) is one of the most abundant and widely distributed copper-bearing minerals, accounting for more than 70% of the earth's copper reserves [], and belongs to primary copper sulfide minerals.Although about 80% to 85% of the world's copper output is produced by means of pyrometallurgical processes, the …
DetailsChalcopyrite is also one of the minerals that are known as Fool's Gold because of how much it looks like gold. But real gold has a more of a buttery yellow color and is more malleable and ductile. Because of its color and copper content, it is also called Yellow Copper. Chalcopyrite is opaque and can be treated with acid to produce a …
