Chalcocite Compared To Chalcopyrite Ore Processing

For pyrrhotite dominant ore types the chalcopyrite grain size is typically coarser with less intergrowths of gangue minerals The chalcopyrite has a higher liberation level in comparison to the pyrite ore types and the copper recovery is higher and a higher concentrate grade is more easily achieved

Investigation of Chalcopyrite Leaching Using an Ore-on

Compared to conventional bulk-scale leach tests, the ore-on-a-chip allows for faster, more efficient screening of leach parameters using real ore samples obtained from mine sites. Insight and optimization of leach conditions is demonstrated here for chalcopyrite, which has been extensively studied, yet leach performance is still strongly dependent on the origin of the ore.

Chalcopyrite represents nearly 70% of known copper resources [3,4]. Pyrometallurgical smelting has been the industry-standard method to extract copper from high-grade chalcopyrite, but the use is restricted due to environmental problems (i.e., SO 2 emissions) and the depletion of rich ore deposits increasing the processing costs [5,6].

This is why Chalcopyrite’s abundance makes it the most significant source of copper ore. The name Chalcopyrite is from the Greek words khalkosor chalkos, which means copper and pyrite, and also strike fire. Chalcopyrite has a hardness of 3.5 to 4, and it’s commonly found in Mexico, Peru, and Australia.
