Abstract
The treatment of lead smelting by-products,such as anode slime and antimony-containing dust and slag is an important process, which is not only related to improvement the rate of comprehensive recovery of resources, but also plays a very important role in improving the economic benefits of plant. The existing by-product treatment technology and current situation were introduced in first. Combined with the current treatment process and characteristics of by-products, this paper focuses on the characteristics of the oxygen-enriched submerged combustion side-blown smelting technology and the application of by-products treatment. Based on the engineering practice and relevant technical and economic indicators of treating 5812t anode slime annually, compared with the conventional technology, this technology has obvious advantages in operation cost, treatment efficiency and environmental protection.
