2. flotation of middling particles i.e. higher than 200 m improves with increased ph. this is true in the case when chalcocite is the major copper mineral. in the case of chalcopyrite ore a lower ph is more desirable i.e. 8.5–9.5 because at a higher ph the flotation of chalcopyrite is decreased especially for the coarser particles.
A flotation pre-treatment study for the separation of enargite cu 3 ass 4 from chalcopyrite cufes 2 ores of different origins was investigated in this work.the copper ore bearing enargite mineral contained 5.87 mass as and 16.50 mass cu while the chalcopyrite bearing ore contained 0.32 mass as and 21.63 mass cu.
About 200 years ago the uk was an important world source of copper and tin and there were mines in cornwall and devon. these mines have now closed and today the biggest copper mines are in chile escondida mine and indonesia grasberg mine. these produce many millions of tonnes of copper ore per year. the main ores of copper are sulfides and ...
Aug 07 2012 jackson sikamo • the effectiveness of chalcocite flotation or any sulphide for that matter will depend heavily on the overall mineralogy acid soluble copper to total coper ratio the gangue matrix and the stability of the ore characteristics in relation to these parameters.
Characterisation of the samples through qemscan showed that bornite chalcopyrite chalcocite and carrollite are the main copper-bearing sulphide minerals while carrollite is the only cobalt-bearing mineral. mineralogical characteristics were averaged per sample to allow for a quantitative correlation with flotation performance parameters.
