Flotation of oxidised chalcopyrite

, 2010
The effect of mineral oxidation on the flotation performance of chalcopyrite was investigated at pH 9.5 as a function of pm1icle size and collector concentration.

Chalcopyrite dissolution rate law from pH 1 to 3

Geologica Acta, 2009
Chalcopyrite dissolution kinetics in the pH range of 1 to 3 were studied by means of long-term flow-through experiments to obtain a dissolution rate law which can be coupled with reactive transport models to forecast Acid Rock Drainage.

Chalcopyrite Dissolution: Challenges

Chalcopyrite is the main source of copper in the world, amounting to nearly 70% of the copper reserves. Nonetheless, chalcopyrite is highly recalcitrant to chemical and biological processing for copper extraction.

Electro-flotation of chalcopyrite

, 1982
Electro-flotation tests were conducted on chalcopyrite particles with a modified Halhmond tube designed for electro-flotation, using platinum anode--copper cathode and graphite anode--copper cathode systems.
