Essay

Тhe thesis deals with questions of processing tungsten- containing secondary row materials (lump used carbide and diamond-carbide tool wastes containing tungsten and hard alloys based on its carbide) with recovering tungsten oxide, natural and man-made dia monds,copper,cobalt and nickel.Kinetic relations (and peculiarities) have been established, and the thermodynamics of interaction of tungsten, carbide and hard alloys with molten binary mixtures (of sodium hydroxide and sodium nitrate or nitrite) has been investigated.
