FIELD: metallurgy.
SUBSTANCE: method of producing coke comprises preparation of a charge from the mixture of coals of various technological grades with petroleum coke of fraction less than 25 mm. Petroleum cokes with different volatile-matter yield are mixed in a given calculated proportion. The amount of petroleum cokes with volatile-matter yield in the range from 7% to 13.9% is not more than 40% of the total charge volume. The petroleum coke is used to prepare the charge with a sulfur content from 1.1% to 6% and an ash content from 0.1% to 2%. The components of the charge are crushed together and the charge is fed to the layerwise carbonization.
EFFECT: optimisation of the coke production process due to obtaining of the charge for carbonization which has an increased efficiency in the production of nickel matte.
