METHOD OF PRODUCING NICKEL MATTE Russian patent published in 2012 - IPC C22B23/02 C10B57/04

Abstract RU 2441082 C1

FIELD: metallurgy.

SUBSTANCE: burden containing pelletised oxidised nickel-containing or and reducing fuel are loaded into shaft furnace. Then, reducing-sulphiding smelting is carried out using coke reduction agent as fuel. Note here that said coke is produced by carbonising the burden containing 5 to 100% of product, the yield of volatile substances making some 14-25%, obtained by delayed low-temperature carbonisation of heavy oil residues.

EFFECT: reduced fuel consumption higher smelting rate of nickel-containing stock, reduced nickel content in slug.
