组合捕收剂KHY反浮选某钙镁质磷矿石

Sudy on Reverse-flotation Test of the New Combined collector KHY for a calcium magnesium phosphate ore

用实验室自制的阴离子捕收剂KHY,对P2O5品位为24.65%的某钙镁质磷矿进行反浮选试验研究。结果表明,捕收剂KHY对温度不敏感,通过"单一反浮选",获得了精矿P2O5品位为35.27%,精矿P2O5回收率80.19%的良好指标。

A laboratory-made anion collector KHY was used to conduct a reverse flotation test on a calcium-magnesium phosphate rock with a P2O5 grade of 24.65%. The results of reverse flotation showed that the collector KHY was not sensitive to temperature. Through the single reverse flotation, a good index of 35.27% of concentrate P2O5 grade and 80.19% recovery of concentrate P2O5 was obtained.
