针对安徽某金铅锌复杂多金属硫化矿选矿指标较低、药剂制度复杂且用量大等问题,分析了原矿的矿物组成及矿石性质,并开展了大量探索性试验,最后提出采用磁选脱除磁黄铁矿—金铅混合浮选—金铅分离浮选—尾矿活化选锌的原则流程处理该矿石。结果显示:闭路试验可获得金含量为43.68×10-6,回收率为46.12%的金精矿;铅精矿中金含量为162.00×10-6,回收率为35.39%,铅含量为38.53%,回收率为72.24%,金的累积回收率达81.51%;锌精矿中锌含量为42.79%,回收率为67.51%。与原有选矿工艺相比,新工艺不仅提高了选矿指标还大幅减少了药剂用量。

For a gold-lead-zinc complex polymetallic sulfide ore in Anhui has a problem such as the low ore dressing indexes,the dosage of reagent system is complex and big.The mineral composition and ore characteristic of raw-ore is analyzed and a large number of exploratory experiments is explored.The last put forward the principle of process to deal with the ore by magnetic separation removal of pyrrhotite,gold-lead bulk flotation,gold-lead separation flotation,activation of tailings flotation zinc.By closed circuit texts can obtain the good indicators,and the gold concent rate with the Au grade of 43.67×10-6 and recovery rate of 46.11%;lead concentrate with the Au grade of 162.00×10-6 and recovery rate of 35.39%, Pb grade of 38.53% and recovery rate of 72.24%,the accumulation of the gold recovery rate is 81.50%;zinc concent rate with the Zn grade of 42.76% and recovery rate of 67.46%.This new method has a better index than the traditional process,as it can not only improve dressing indexes,but reduce a lot reagents dosage.
