Abstract:
The development of primary lead metallurgy is connected with application of modern metallurgical processes, including Vanyukov process. The history of creation and development of this way of Vanyukov process is described together with its following advantages:
-absence of strict requirements to composition and quality of raw materials;
-possibility of raw materials processing without drying and complex smelting preparation;
-possibility of using oxygen-containing blowing with various oxygen content;
-obtaining gases with high content of sulfur dioxide;
-combination of smelting with in-furnace refining of lead bullion;
-possibility of usage of various fuel types.
Vanyukov furnace allows to carry out the continuous consecutive oxidative and reduction processes in one unit. As the need arises, the furnace allows to carry out these processes by consecutive cyclical runs. The basic physical-chemical smelting parameters are described. Nowadays, new ways of lead raw material smelting are developed: processing of complex raw materials, containing copper and zinc; processing of semi-products, containing copper, lead and zinc; and processing of raw materials with high content of noble metals.
