Title:
MANUFACTURING METHOD USING COPPER AND IRON CONTAINING MIXING SLAG
Document Type and Number:
WIPO Patent Application WO/2019/071788
Kind Code:
A1
Abstract:
A manufacturing method using a copper and iron containing mixing slag. The manufacturing method comprises the following steps: S1, slag mixing: putting a copper slag into a smelting reaction device, adding one or more of a lead smelting slag, a blast furnace slag, a steel slag and a ferro-alloy slag to form a mixing slag, adding one or more of a copper oxide mineral, a copper sulphide mineral and a copper-containing material, and homogeneously mixing the described materials, heating the mixing slag to a molten state to be used as a reaction slag, monitoring the reaction slag in real-time, and obtaining through regulation a post-reaction slag; and S2, separation and recovery. The method can deal with a hot slag, thus making full use of a molten copper slag and a molten metallurgical slag and physical thermal resources and hot metallurgical fluxing agents, and can also deal with a cold slag, thus achieving metallurgical modification to the slag by slag mixing or cold mixing; problems in high efficient recovery and use of metallurgical resources and thermal energy and environmental pollution are effectively solved.
