  • Pyrometallurgical method and furnace for processing heavy nonferrous metal raw materials
    Patent number: 4294433
    Abstract: A method for processing heavy nonferrous metal raw materials by heating and melting said raw materials in a molten slag with the formation of a heterogeneous melt consisting of a sulfide and an oxide phases. The melt is bubbled oxidized by injecting a gas containing not less than 35% oxygen at an intensity of about 200 to about 2000 m.sup.3 STP/h per square meter of horizontal section of the melt, with the effect that the melt is divided into a top bubbled part and a bottom calm part comprising a slag layer, a matte layer and/or a crude metal layer, each of which is tapped separately. A furnace for putting said method into effect is a shaft terminating in its bottom part by a hearth and having devices for tapping smelting products, whereas the top part is provided with orifices for feeding a charge and removing gaseous smelting products. The furnace has cooled side tuyeres set at a level dividing the shaft into two vertical parts.
