TH29583C3 - Method for Producing Copper Blister in Suspended Reactors - Google Patents

Abstract

DC60 The invention involved a method of producing copper blister by smelting. The heat in the suspended reactor directly from the copper blister sulfide concentrates. According to the method, the copper sulphide concentrates are then fed into the suspended reactor in which the cooled copermats are cooled. And the finely milled will also be fed. To receive the heat released from the concentrate The invention involved a method of producing copper blister by thermal smelting in a direct suspension reactor from copper blister sulfide concentrates. According to the method, the copper sulphide concentrates are then fed into the suspended reactor, where the matt copper is cooled and finely ground to obtain a Hot released from the concentrate
