一种磷矿低温浮选捕收剂

A collector applied to the flotation of phosphorite ores at low temperature

探讨了一种自制的磷矿浮选捕收剂在低温（13～15℃）条件下的浮选效果，同时做了加温（28-30℃）条件卡的对比试验．在低温条件下精矿的品位达到30．40％，回收率达到81．36％；在加温条件下精矿的品位达到30．55％，回收率达到82．37%，由此可知这种捕收剂受温度影响不大，能在不加温的条件下用于冬天生产．

The paper studied the flotation at low temperature （13-15℃）, the contrastive experiments at temperature 28 - 30℃ were done meanwhile. Test results show that the recovery and grade of phosporite can reach 81. 36% and 30.40% at 13- 15℃ ; and that the recovery and grade can reach 82.37% and 30.55% at 28-30℃. The conclusion that the effect of temperature on the collector is tiny can be reached from this paper. The collectorocan be used to the flotation in winter consequently.
