FIELD: metallurgy.
SUBSTANCE: this process comprises preparation of the charge by mixing the titanium-bearing slag with aluminium and calcium-bearing material. The latter represents calcium fluoride and calcium, of calcium fluoride and calcium oxide, or calcium fluoride and the mix of calcium and calcium oxide. Here, the ratio between titanium dioxide, aluminium powder and calcium and/or between calcium oxide and calcium fluoride makes 1:(0.58-1.62):(0.28-1.1):(0.09-0.32). Besides, it includes reducing fusion of said slag at 1450-1750°C and separation of the alloy from said slag.
EFFECT: higher quality of the alloy and titanium extraction, better separation of the alloy from slag.
