The invention is used to produce coke for melting in shaft furnaces during production of the non-ferrous metals, in particular, during nickel production. Improved physical and chemical properties of coke suitable for use in production of non-ferrous metals are provided due to a coking additive made of crude oil cracking waste. The coking additive with a sulphur content of 3.5-4.5% of the additive weight is mixed with coal concentrates of gaseous caking coals, gaseous caking lean coals, gas coals, coke low-caking coals at components ratio, wt.%: coking additive 50-70; coal charge 30-50. |
