Procedure for the extraction of Copper from copper sulfide Concentrate containing Arsenic

摘要

p Procedure for the extraction of copper from a concentrate of copper sulfide containing arseacute; comprising the procedure: carrying out the atmospheric oxidative leaching of a feed suspension that includes the concentrate of copper sulfide containing arseacute; and an acidic leaching solution containing iron sulfate, in the presence of oxygen to produce a leaching suspension that induces copper and arseacute dissolved in the leaching solution; nbsp; after dissolving the copper and arseacute; unique,The seeds containing scorpion are put into glycol suspension to induce the precipitation of arsenic and formaldehyde; eacute; Nico dissolved during the oxidation leaching is used as scorpion; solid is extracted from the suspension of leaching liquid to produce solid, including scorpion, The leach solution is filled with copper, and the iixiviation solution is extracted together with solvent to recover copper, so as to produce a kind of refining, including amp; Aacute; sulfuric acid and ferric sulfate;a. Recycle Al amp; nbsp; minus one porci amp; oacute; N, including diethylene glycol; Aacute; sulfuric acid and ferric sulfate, for oxidation leach; / P
