The Latest Development of Oxygen Bottom Blowing Lead Smelting Technology

摘要

The world's largest lead smelting plant using oxygen bottom blowing (SKS) lead smelting technology under construction is introduced in the paper. The most advanced smelting and environmental protection technologies are applied in the design and construction of the plant, representing the latest development level of SKS lead smelting technology. The secondary bullion is produced by the process of oxygen bottom blowing reduction (RSKS) furnace. Zinc oxide is recovered from the RSKS furnace slag by fuming furnace. The refined lead is produced by continuous refining furnace, anode formwork erection cast, and large plate electrolysis process. The world's largest single series lead smelting plant is introduced from five aspects including treatment scale raw materials, technological process, furnace and the main technical specifications.
