CLEAN METHOD FOR COPPER PRODUCTION FROM MINERAL RAW WITH LOW CONTENT OF COPPER

摘要

Improved method for chemical and bacterial extraction of copper from mineral raw material at lower environmental cost is elaborated. The conventional technology is complemented with an adsorption stage of removal of the excess iron(III) from the liquors after the stage of bacterial regeneration of the acidic leaches containing metals and before the stage of cementation of the copper. The managed optimisation of the metals composition in the liquors improves the effectiveness of the processes and the characteristics of the target metal.
