Abstract：

This article analyzes the role of oxygen in lead zinc metallurgy, including shortening the metallurgical process, promoting energy conservation and environmental protection, improving metallurgical strength, enhancing raw material adaptability, and enhancing comprehensive recovery efficiency. This article introduces different lead zinc metallurgical processes and their oxygen consumption characteristics, including oxygen enriched side blowing lead smelting, oxygen bottom blowing lead smelting, oxygen enriched top blowing lead smelting, flash smelting lead, oxygen pressure leaching zinc smelting, and atmospheric pressure oxygen leaching zinc smelting. It is pointed out that oxygen enhanced metallurgy is the direction for the transformation and upgrading of lead zinc metallurgy.

Key Words：

lead zinc metallurgy; oxygen rich smelting; oxygen pressure leaching; energy conservation and emission reduction
