The Latest Development of Oxygen
Bottom Blowing Lead Smelting
Technology
Weiguo Wu, Pengfei Xin and Jianming Wang
Abstract 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.

Introduction
SKS lead smelting technology is one of the world’s most advanced lead smelting
technologies. More than 80% lead production is adapt SKS technology. The application of SKS lead smelting technology greatly increases the automation degree of the
lead smelting process, improves the operating environment, and reduces the three
wastes emission and the production cost, which has become the world’s most widely
used lead smelting process.
Since the first SKS furnace was put into industrial application, the SKS lead
smelting technology has made great progress after nearly 20 years of production
practice and application. The reduction process of blast furnace is gradually replaced
by the reduction process of bottom blowing melting furnace. The annual production
