新型复合药剂的试验研究

以七台河桃山矿煤样为研究对象,进行了OP、合成酯及KJ3种复合药剂的浮选效果的对比实验,确定了KJ复合药剂为最佳药剂。将KJ复合药剂与常规药剂的试验结果相比较,在药剂耗量相同的条件下,KJ复合药剂的精煤产率提高了10·06%,浮选完善指标提高了5·14%,KJ复合药剂的浮选速度也明显加快。 The coal sample from Taoshan was the main object in this study. The flotation effect contrast tests of three kinds of complex reagents i.e. OP,synthesis ester and KJ were conducted. The KJ complex reagent was ascertained as the optimal reagent. Comparing with conventional reagents the KJ complex reagent increased the clean coal yield by 10.06%,the flotation perfect index by 5.14% and the speed of the flotation under the same agent consumption
