The bornite mineral was obtained from the geological museum of Guangxi Province of China, and the marmatite mineral was obtained from Dachang Mine of Guangxi Province of China. These minerals (bornite and marmatite) were of high purity with >90% wt% purity using powder X-ray fluorescence (XRF). Please see the ESI Table S1† for elementIntroduction. The copper-iron sulphide mineral bornite (Cu 5 FeS 4) is a ternary semiconducting material that crystallises in the orthorhombic system and one of the main valuable sources of commercial copper after chalcopyrite (CuFeS 2) and chalcocite (Cu 2 S) in chronology of economic importance (Buckley et al., 1984).

Minerals Free Full-Text Sequential Bioleaching of Pyritic
In this work, we proposed a method for biohydrometallurgical processing of mining (old pyritic flotation tailings) and metallurgical (slag) wastes to recover gold and other nonferrous metals. Since this processing allows the removal of toxic metals or at least decreases their content in the solids, this approach may reduce the negative The method of mining and whether To find the fraction of copper in bornite, divide the total weight of copper in the mineral, 320, by the molecule weight, 504. 320/504 = 0.63; 0.63 *100 = 63% of copper per molecule of bornite.
