Resumen
A method of intensive, continuous copper fire refining, said method comprising the stages of: continuous tapping in a liquid copper (4) into a first oxidation reactor; liquid copper oxidation with combustion gases containing oxygen or with air; simultaneous formation of slag collecting impurities; continuous tapping out of oxidized copper and refining slag from the first reactor (8); continuous tapping in of oxidized copper into a second reduction reactor; reduction of copper with carbon and reducing gases formed by partial combustion of fuel and carbon; and continuous tapping out of reduced copper (14).
