Abstract:
A method for producing blister copper directly from copper concentrate is provided, comprising: a) adding copper concentrate, copper matte, slagging material, oxygen enriched air, endothermic material to an upper segment of the reaction furnace; b) adding reducing agent to the lower segment space of the reaction furnace; c) directing the produced hot coke and liquid slag into an electric furnace, and adding copper concentrate into the electric furnace to generate an electric furnace slag and copper matte; d) the copper matte being granulated and finely ground, then re-fed into the reaction furnace.
