摘　　要：对某磷矿进行了分级浮选探索试验。结果表明:与传统正—反浮选相比,分级浮选不仅能提高精矿的品位和回收率,而且能降低药剂的耗量。分级浮选对正浮选的影响大于反浮选。Classification-flotation tests were conducted on certain phosphorus ore sample.The results showed that classification-flotation obtained higher grade and recovery of P2O5 concentrate with the lower reagent ration than normal direct-reverse flotation.Classification-flotation had greater influence on direct flotation than reverse flotation.
