反浮选脱硅捕收剂研究

Study on Reverse Flotation Collector for Removing Silicate

在常温条件下采用反浮选碳酸盐—脱泥—反浮选硅酸盐的双反浮选工艺对海口磷矿Ⅰ、Ⅱ采区原生矿进行了选别试验。第二段反浮选用新研制的ＳＬ－２０阳离子捕收剂获得了较理想的分选效果。

The double reverse flotation process,i.e. reverse flotation carbonate,removing slime and reverse flotation silicate was used to beneficiate the primary mineral of Ⅰ、Ⅱ mining district of Haikou Phosphate Mine in the laboratory.New developed SL-20 cation collector used to the second phase of reverse flotation got ideal beneficiation effect.
