Abstract:

Special double-chamber Vanyukov furnace was designed in 2004 at Southern Urals Nickel Plant, for the purpose of laterite ore (~1% of Ni) matte smelting. The following operations were carried out during full-scale tests and application of new smelting complex:
-use of controlling methods of smelting stage temperature modes in first furnace chamber, and reduction-sulfiding processing of slag melt in second chamber;
-use of regulation methods of nickel mate composition, continuous loading of charge and reagents, and output of slag and matte.
The basic production data of new technology is given. The technological peculiarities of cokeless smelting of laterite ores in Vanyukov furnace are set, showing the wide prospects of its industrial application.
