Chalcopyrite Ball Mill
chalcopyrite flotation company
Chalcopyrite Flotation without Collector Surface Chemistry. It has been reported that chalcopyrite can be floated selectively from an ore containing pyrite, sphalerite, and silicious gangue minerals without using a collector. Sodium sulfide was used as a promoter, presumably to clean the chalcopyrite surface of its hydrophilic oxidation products.
Recovery of copper from a surface altered chalcopyrite ...
Bioleaching studies for chalcopyrite contained ball mill spillages are very scarce in the literature. We developed a process flow sheet for the recovery of copper metal from surface activated (600 ...
Oxidation of chalcopyrite by extended milling
Chalcopyrite has been milled for up to 50 h in oxygen, air and argon atmospheres using a laboratory ball mill. No phase changes were evident in argon but the XRD peaks were weaker and broader indiing crystalline refinement. In oxygen, even after 1 h milling peaks for CuSO4•5H2O were present and these became predominant after 20 h milling where the chalcopyrite peaks were absent.
