中文摘要: 以电弧炉炼锡产生的废渣为原料,盐酸为浸出剂,在温度40 ℃、液固比25︰1(mL/g)、搅拌速度250 r/min的条件下进行锡的富集。废渣中的锡含量由1.82%富集到13.61%,富集后的废渣再经酸浸、锌置换处理后,最终获得纯度98%的金属锡,锡回收率达99.5%,硅组分和钙组分的脱除率分别达到83.42%和94.21%,可以作为副产物出售,实现二次资源化。
Abstract:Tin was enriched from tin-smelting waste slag in electric arc furnace with hydrochloric acid as leaching agent under the conditions including temperature of 40 ℃, ratio of liquid to solid of 25︰1(mL/g), and stirring rate of 250 r/min. The results show that tin content in slag is enriched from 1.82% to 13.61%, and metal tin with purity of 98% is recovered with tin recovery of 99.5% from enriched slag by further acid-leaching and zinc replacement. The removal rate of silica and calcium, which can be sold as by-products, is 83.42% and 94.21% respectively.
