Title:
METHOD FOR PRODUCING SMELTING SLAG FROM NICKEL
Document Type and Number:
WIPO Patent Application WO/2019/071798
Kind Code:
A1
Abstract:
A method for producing smelting slag from nickel, comprising the following steps: S1, mixing furnace slag: adding nickel smelting slag into a smelting reaction device, and adding a calcium-series mineral and an additive; stirring, heating the slag to a molten state, adding one or more from among a copper oxide mineral, a nickel oxide mineral, a copper sulfide mineral, a nickel sulfide mineral and a copper-containing material; mixing well, using the mixture as reaction slag, monitoring in real time, and simultaneously obtaining the slag after a reaction by means of adjusting the mixed copper-containing slag to simultaneously satisfy conditions a and b; S2, separation and recovery. The method may process hot slag, and cold slag may also be processed, while copper-containing furnace slag may be processed and a copper oxide mineral and/or a nickle sulfide mineral may be processed by fully using the physical thermal resources of molten nickle smelting slag as well as metallurgical flux, thus achieving the simultaneous production of copper and iron.
