从磷铁共生矿石中浮选磷灰石试验研究

摘要

研究了从国外某磷铁共生矿石中浮选磷灰石.用BK420-C作捕收剂,经过一次粗选、一次扫选、三次精选,浮选精矿中P2O5品位为35.01%,回收率为52.81%,浮选效果较好.%Flotation of phosphorite from a oversea phosphorus-iron paragenesis ore was studied.Using BK420-C as collector,by the flowsheet of one roughing,one scavenging and three choiceness,the concentrate grade and recovery rate of phosphous pentoxide are 35.01% and 52.81%,respectively.The flotation effect is better.
