material, and also the lump material with no need for the flux or coal needs preparation and drying. In addition, it is characterized by low investment, large specific
throughput of the furnace, flexible capacity, and convenient operation.
Description of Oxygen-Enriched Air Side Blown Furnace
The oxygen-enriched air side blown process is developed based on the Vanyukov
process invented by the former Soviet Union, which is an oxygen-enriched air side
blown bath smelting process. The furnace hearth is made of refractory materials,
and the furnace body is made of copper jacket and steel jacket. A copper water
jacket is provided with several primary tuyeres for blowing oxygen-enriched into
the melt slag layer. The furnace charge is fed from the upper feeding port, and the
blown oxygen-enriched strongly agitates the upper melt to quickly complete the
smelting process. Since 1976, this process has been widely used for copper and
nickel smelting in the former Soviet Union. China has conducted the improvement
re-innovation on the basis of Vanukov furnace; the commercial-scale test on the Pb
smelting by oxygen-enriched air side blown process was started in 2001, and in 2009,
it was successfully applied for the reduction in hot high-Pb slag. The research on
the processing of lead-bearing polymetallic materials by this process began in July
2012, and the commissioning was conducted successfully at one go on June 1, 2014
