Abstract

The degree of extraction of metals from oxides depends on a number of physical and chemical factors: temperature conditions of melting, melting rate of the charge, the completeness of diffusion processes. Speed combustion parameters defined under the joint recovery of tungsten oxide and iron trioxide and the factors influencing the rate of combustion of the mixture. The burning rate of the charge is one of the key parameters that affect the performance (yield of alloy, metal recovery) of metallothermic process. It has been found that to obtain a metal alloy and aluminum to efficiently introducing ballast from 10 to 20%. The rate of combustion of WO3 – 17,2–17,9 g/cm2 · s, for Fe2O3 – 2,0–2,25 g/cm2 · s.
