摘要
原矿为高含泥高氧化率低品位铜矿。根据矿石的工艺矿物学特性,开展"直接浮选"、"预先脱泥+浮选"和"酸浸"三种工艺流程试验。试验结果表明,"酸浸"是最佳的提铜工艺流程。在较佳的酸浸工艺条件下,可获得铜浸出率92.09%,硫酸耗量54kg/T的技术经济指标。
The raw ore is the high mud, high oxidation and low grade Cu ore. According to the technological and mineralogical characteristics of it, we have carried out ＂direct floatation＂, ＂pre - remove of mud ＋ floata- tion＂ and ＂acid immersion＂ 3 technological flow charts, which shows that the ＂acid immersion＂ is the best one. Under the good ＂acid immersion＂ technological condition, the Cu leachability can be 92. 09% and the con- sumption of sulfuric acid 54 kg/t.
