湖北远安磷矿成分分析及磷富集实验
Industrial Minerals and Processing(2011)
Abstract
以市售湖北特大磷矿区内远安县荷花镇品位较低的磷矿为样本,分析了该磷矿石的成分,得出该磷矿石中各主要成分的质量分数为:P<,2>O<,5> 24.04%,CaO 49.17%,Fe<,2>O<,3> 1.49%,Al<,2>O<,3> 1.95%,MgO 3.22%,SiO<,2> 7.32%.基于此数据,本文采用了稀硫酸方法对该矿石进行了富集实验研究.富集后P<,2>O<,5>品位可以提高至29.91%,接近于富矿P<,2>O<,5>品位,且其他对磷肥生产有害的杂质的质量分数也降低了,富集后的磷矿可以满足生产14%过磷酸钙的要求.
