New Method for the extraction of Copper from mixed MINERALS (oxides more Copper sulfides) with or without calcareous Gangue leaching with acid, sulfamico

摘要

Concerning a procedure for the extraction of Copper from mixed Copper Ore with or without calcareous Gangue leaching with acid sulfamico comprising: (a) to Grind and classify the Mixed complex of Copper Ore, Leaching the Ore (b) systems and percolantes in agitated Systems.(c) add the sulfamico acid dissolved in aqueous solution as leaching Reagent Mixed Copper Ore to produce a series of reactions with Calcium Carbonate, Copper oxides such as cuprite tenorite Malachite, among others, Copper sulfides and native Copper Sul. Fato COPPER (ii) as the main product in the Rich Solution (PLS), or loaded(d) clarify and filter and purify the PLS, PLS) through the process of solvent extraction to obtain the Rich electrolyte of high purity Copper sulphate (f) to precipitate the calcium content in the rafinato (Effluent from the process of solvent extraction) in the pool of rafinato, H) Electrodepositar Copper content in the elctrolito Rich,In electrolytic cells of electrowinning Copper metal with a purity of 99.999%
