摘要
采用浮选———酸浸湿法工艺处理锌尾矿，研究了浮选药剂的最佳配比。以湿法处理浮选得到的锌精矿（βｚｎ＝３６．５％，εｚｎ＝５６．７％）。可制得符合国标ＧＢ８２５１－８７的饲料级ＺｎＳＯ４·７Ｈ２Ｏ。
The technique of floatation acid leaching wet processing has been employed to the preparation of zinc sulfate from zinc tailing. The optimum composition of the floatation reagents was studied. The grade and recovery of zinc concentrate floated were 36.5% and 56.7%, respectively. The feed grade zinc sulfate produced comes up to the national standard GB8251-87.
