摘要
为了改善金属氧化矿和非金属矿加温浮选的现状,降低选矿成本.以菜籽油脚为基本原料,经皂化后再与松香钠皂相混合,并加入非离子表面活性剂Tween-80,可获得乳化效果较好的复合捕收剂SYT-1.该复合捕收剂常温下就能在水中充分分散,捕收能力较强.与氧化石蜡皂浮选磷矿石的对比试验表明,其效果明显优于氧化石蜡皂.原矿P2O5品位为9.02%,经一粗一精一扫的闭路试验取得了理想的指标,精矿P2O5品位达30.12%,P2O5回收率达91.26%.
In order to improve the present state of the heated flotation of nonmetal ores and metallic oxideore, and decrease the cost of flotation, a new flotation collector is prepared with colza oil foots as the raw material. The material is saponified first, then mixed with sodium rosin soap and added nonionic surfactants Tween-80 which can improve the efficience of emulsification of the plant oil rejectament. The compound collector SYT-1 can disperse well in water at normal temperature and has good collective performance. The contrast flotation experiments between the compound collector SYT-1 and paraffin oxide soap were carried out, and the results show that the efficience of the compound is obviously better than that of paraffin oxide soap. Grade of P2O5 in crude ore is 9.02%, and through the closed circuit test of one roughing, one cleaning, and one scavenging system, ideal indices were achieved： grade of P2O5 in concentrate 30. 12%, and the recovery of P2O5 in concentrate 91.26%.
