Abstract

Abstract

An novel approach has been proposed for treating solid ferrous scrap with sulphide matte by blowing the gas with a controlled low oxygen pressure to promote the removal of copper. It has been proved by comparison of the result of the experiment by blowing argon at 950℃ with those of the static experiments that argon stirring can remark-ably increase the rate of copper removal at the initial stage of the treatment, for the matte of 70% FeS and 30% (mass fraction).
