Title: Method for producing blister copper directly from copper concentrate
Inventor: ZHOU SONGLIN
IPC: C22B5/02
Filed: 2012-10-24
Abstract: The present invention provides a method for producing blister copper directly from copper concentrate, comprising: a) adding copper concentrate, copper matte, slagging material, oxygen enriched air, endothermic material to a 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. The addition of reducing agent in the lower segment will not increase the heat load of the reaction furnace since the reducing agent does not burn. Over-oxidized Cu 2 0 and Fe 3 0 4 are reduced by hot coke, which improves the direct recovery rate of copper, improves the character of the slag, and also controls the amount of Cu 2 0 and Fe 3 0 4 contained in the slag by controlling the thickness of hot coke layer; copper matte back to the reaction furnace can reduce the amount of Fe in the reaction furnace, thereby reducing the oxygen demand and heat generated in the reaction furnace, reducing furnace gas amount and heat load, therefore can process low-grade copper concentrate with high Fe and low Cu.
