ABSTRACT:
The blast furnace in the present invention comprises a V-shaped or an inclined hearth, tuyeres disposed along said hearth, a tap hole for discharging matte and/or slag, said tap hole being disposed at the lowest part of the hearth, and dampers having V-shaped or inclined fore end, each of said dampers being disposed to agree with said tuyeres. The present blast furnace, when employed for smelting by feeding briquetted Zn bearing materials as the material thereto and blowing preheated air therein through the tuyeres disposed along the hearth, displays an improved smelting efficiency in separating and recovering volatile valuable metals and non-volatile valuable metals.
