Abstract:
Nowadays, more than a half amount of lead is produced from secondary raw materials. Basically, the production is carried out in developed countries, which have strict economic requirements. The absence of noble metals in raw materials leads to reduction of industrial and capital costs. Vanyukov furnace meets these requirements because of its high production capacity and its blowing-based operation with high oxygen concentration. Besides, the furnace does not require the complex preparation of raw materials to smelting process. The smelting development history started in 1980-s (when the first works were carried out under the direction of Professor Andrey V. Vanyukov, with participation of VNIITsvetmet Institute), and continues nowadays with modern offers of creation of secondary lead production. The basic physical-chemical regularities of secondary raw material smelting and the influence of various parameters on Vanyukov process indicators are considered. Basic production indicators are described together with their possibilities and prospects.
Key words: chemistry, secondary lead, Vanyukov furnace, antimony, tin, arsenic, refining, ecology, silicate slag, sulfur.
