LEACHING OF LOW-GRADE COPPER ORES: A CASE

2017-6-9 · During the leaching of the ore with sulphuric acid concentration of 0.1 and 0.01 M H2SO4, leaching degree of total copper ranged from about 27 to about 55 %, respectively. Given that the degree of leaching of total copper was larger than the amount of oxide copper present in the sample (41 %), it can be concluded that an oxidation reaction occurs between copper sulphide minerals, followed by dissolution of so formed oxides. The copper content in the leach solution has reached, after 5 days about 1 g dm3 (Fig. 3a). At the very beginning of the process (first two days), around 67 % of copper oxide was leached, after and after 10 days of leaching, leaching
