复合精矿含13.38Cu和3.75％Sb,与含Cu黄铁矿精矿混合,并使之含S达27.1％。混合物料经9小时700℃的烧结后在旋涡炉中熔炼,结果94.8％Sb富集于烟尘,所得冰铜达51.32Cu和0.43％Sb。
The composite concentrates contain 13.38Cu and 3.75% Sb, which are mixed with Cu-containing pyrite concentrate and contain 27.1% S. The mixture was smelted in a vortex furnace after sintering at 700 ° C for 9 hours. As a result, 94.8% of Sb was enriched in soot and the resulting attapulgite reached 51.32 Cu and 0.43% of Sb.
