Abstract:A factory smelt high grade scrap copper with 300 tons of stationary anode furnace, the slag produced contains 25%~35% copper. Due to the lack of slag smelting recovery equipment, these slag with high copper content can only be sold directly at a discount, resulting in a large loss of copper in smelting production. In order to reduce the copper content of smelting slag, based on the analysis of the impurity composition and content of copper materials, combined with copper metallurgy principle, the appropriate type of slag was selected, the control situation of copper content in slag with different slagging agent in smelting was tested and finally a composite slagging agent was finally found that is beneficial for controlling the copper content in the slag. In industrial production trials, the production operation process is optimized respectively from the slag type selection, oxidation time, slag temperature control, heat preservation time and slagging agent ratio, and the ultimate goal of controlling copper slag below 18% has been achieved, which can significantly reduce the loss of slag sales.
