Title:
A METHOD FOR TREATING A LATERITE-NICKEL ORE SURFACE ORE BY MEANS OF A THREE-STAGE REDUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/021466
Kind Code:
A1
Abstract:
A method for treating a laterite-nickel ore surface ore by means of a three-stage reduction method, which belongs to the technical field of steel smelting, comprising the three steps of a fusing agent-free solid state reduction stage, a magma evolution reduction stage and a fractional reduction refining stage, wherein the method can finally produce a nickel chromium-containing base alloy steel or a low-nickel-iron and an aluminate cement clinker. By employing non-coke smelting, the high value recovery of alloying elements and resource utilization of waste Al 2O 3 in the laterite-nickel ore surface ore, which is difficult to treat using existing technology, are realized at a low cost, and the method has a high economic value.
