Pb direct smelting process allowing for the processing of Zn smelting slag blended with the furnace charge
This invention discloses a Pb direct smelting process, allowing for processing of Zn smelting slag blended with the furnace charge. This process is characterized by short circuit. highly flexible raw material, allowing for smelting of Pb＞25% low grade charge, production of lead bullion just in one metallurgical furnace with lead content in the slag controllable at <3.5% to eliminate the blast furnace or other equipment for highPb slage reduction. Thus, this process is a real Pb directing smelting or Pb smelting just in a single furnace.
