METHOD OF PREPARATION OF CHARGE FOR SMELTING TITANIUM SLAG IN ORE FURNACE Russian patent published in 2017 - IPC C22B34/12 C22C33/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, particularly to making metallic titanium from titanium slag, specifically to preparing charge for smelting titanium slag in ore furnace. The method includes crushing of a carbonaceous reducing agent, metering and mixing it with an ilmenite concentrate to make the charge, transporting and loading the charge to the ore furnace bins. After crushing the carbonaceous reducing agent is dried to mass residual moisture content of up to 5 wt %, coal wastes are recovered from filters during gases cleaning from the process of the carbonaceous reducing agent preparation, the coal waste is loaded into a mixer where a liquid binder is delivered under the weight ratio S:L equal to (3-7):1 and stirred to make a pasty mass which is formed into briquettes and dried, the briquetted coal waste is mixed with the carbonaceous reducing agent under the weight ratio of briquetted coal waste:carbonaceous reducinf agent of 1:(15-25) and the made mixture is mixed with the ilmenite concentrate for making the charge for smelting of titanium slag.

EFFECT: invention reduces the costs of raw materials and materials, the cost of titanium slag and environgmental emissions of waste products.
