Sustainable Mining and Metallurgy

A smelter upgraded the traditional Ausmelt oxygen enriched top blown bath smelting furnace and P-S converter into a top side blown composite bath smelting furnace and a multi gun top blown furnace, and cancelled the settlement electric furnace matching the Ausmelt furnace, realizing the transformation and upgrading of the traditional smelting process to the green low carbon short process continuous copper smelting process. This paper systematically expounded the operation of the process system and the main technical and economic indicators, introduced in detail the production operation points of the furnace opening and stopping operation, and summarized the prevention of accidents such as foam slag control, water leakage of water jacket and combustible gas explosion. After the process transformation, the production is continuous and stable, and high grade copper matte and high quality crude copper are stably produced. The copper content of the smelting slag is less than 2%, and the unit cost of anode copper is reduced by about 330 yuan. The process has significant advantages in energy saving and environmental protection, reducing air pollutant emissions and reducing production costs.
