Process for the selective separation and obtaining of copper from cuprous solutions, characterized in that, conveniently, copper (II) salts are reduced in chloride solutions to copper (I) salts, copper chloride is precipitated and separated; the copper chloride is then reacted with aqueous suspensions or solutions of alkali hydroxides and carbonates, oxides and hydroxides of earthy alkali, to copper oxidide at a higher temperature, preferably at 60-80ยบ c, the reaction is carried out continuously and the copper oxidic is melted reducing in the vat or reverberatory furnace.
