摘要:
为了有效地排除滇池周边某中低品位硅质胶磷矿浮选精矿中铁、铝杂质,以减小后续加工的处理难度,有效利用磷资源,对这种硅质胶磷矿进行了试验研究；采用分级浮选、分段加药的浮选方法,获得磷精矿P2O5质量分数为30.48%、MgO质量分数为0.66%和铁、铝杂质质量分数为（R2O3）1.65%的指标,达到一级酸法磷肥对磷精矿铁、铝杂质的要求,能够降低磷肥加工的生产成本.
Abstract:
In order to effectively rule out iron and aluminum impurities of flotation concentrate of a mid low grade silicon collophanite around the Dianchi Lake, to reduce the handling difficulty of subsequent processing, and effective use of phosphorus resources, this paper carried out its experimental study. The authors adopted a classification flotation and section dosing methods, and obtained phosphate concentrate:P2O5 30.48%, MgO 0.66% and iron and aluminum impurities (R2O3) 1.65%. The firstgrade requirements on iron and aluminum impurities of acidphosphorus fertilizer with phosphate concentrate, and the production cost of phosphate fertilizer processing was reduced.
