Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).

Mar 10, 2015 Stirred milling is an enabling technology to process low grade finely disseminated ore bodies. Besides size reduction, stirred mill has the ability to deliver high energy to particles which facilitate crystal structure distortion. High energy stirred milling experiments (up to 300 kWh/t) were carried out on chalcopyrite concentrate.

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 indicating 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 …

Sampling was performed by coning and quartering method. Intensive milling experiments were carried out in a FP2 four milling jar planetary ball mill (Fara-pajouhesh, Iran). Milling jars were made of tempered chromium steel (11.5%Cr, 2.1%C, 0.7%W) having a volume of 125 ml. Milling balls were made of stainless steel (0.45%C, 13%Cr). More

Chalcopyrite ore was obtained from the Quebrada Blanca mine in northern Chile. The ore contained 0.52% copper, with > 95% of that copper being present as chalcopyrite.Prior to use, the ore was crushed to − 13 mm, resulting in a P 80 of 11.4 mm and a fines (− 150 μm) content of 4%. Table 1 details the chemical composition and mineralogy of the chalcopyrite …
