METHOD FOR ALUMINOTHERMAL SMELTING OF FERROTUNGSTEN Russian patent published in 1995 - IPC

Abstract SU 1764331 A1

FIELD: ferrous metallurgy. SUBSTANCE: tungsten-containing oxide wastes are charged after melting through of the first portion in mixture with calcium hydroxide or carbonate with mixture component ratio of 1:(0.01-0.1) in the amount of 0.02-0.1 from the weight of the first portion. EFFECT: higher recovery of tungsten and reduced material costs for smelting due to reduced amount of return metal wastes. 1 tbl
