FIELD: metallurgy.
SUBSTANCE: procedure consists in drying crude ore, in separation ore into fractions +2 mm and -2 mm, in mixing small fractions of ore -2 mm with sulphidiser, flux and coke breeze and in briquetting. As flux there is added shale with 8.0-10.5 % weight of its contents in charge. Nickel sulphidiser containing 10-25 % wt of sulphur, not less, than 5 % wt of nickel and iron are introduced to charge as sulphidiser. Amount of sulphidiser added into charge is 20 % wt.
EFFECT: raised extraction of nickel into matte at simultaneous decrease of specific consumption of coke at melting briquettes out of oxidised nickel ore in shaft furnaces.
