Gipronickel Institute JS that is a Research and Development Centre affiliated to the worldclass Norilsk Nickel Mining and Metallurgical Company, and Outokumpu Technologies AB (Boliden Contech AB) have jointly developed the reconstruction project of Pechenganickel metallurgical operations using a two-zone Vanyukov furnace. The international expert group appointed by the Nordic Investment Bank has examined the project. The project financing should be partly executed by the Norway government. Current annual rate of sulfur dioxide emissions is 100 000 t. The aim of the project is to reduce it to 12 000 tpy._x000D_
Pechenganickel Combine is owned by MMC Norilsk Nickel. Currently it produces nickel high-grade matte from sulfide copper-nickel concentrate with up to ten per cent MgO content. The existing production is in accordance with the following flow sheet: agglomeration - electric furnace smelting with matte production - converting in horizontal converters. Annual production capacity is about 36 000 t of nickel in high-grade matte. Converter gases report to sulfuric acid production._x000D_
The principal results of studies on high magnesia materials smelting in two-zone Vanyukov furnace, engineering solutions, and technical and economical parameters are offered._x000D_
