摘要
针对湘西某碳质胶磷矿进行了选矿试验研究。原矿P2O5品位约为20%,MgO含量6.70%,SiO2含量11.81%,S含量2.93%,针对该矿在常温下采用"脱碳-脱硫-脱镁"反浮选试验流程,最终得到了P2O5品位28.19%、回收率78.47%的磷精矿产品,实现了磷矿的有效回收和富集。
Experimental study on mineral processing technology of a carbonaceous phosphate rock from Western Hunan was conducted.The P2O5,MgO,SiO2 and S contents in this raw rock are about 20%,6.70%,11.81%and 2.93%,respectively.By adopting a reverse flotation flowsheet comprising sequentially decarburization,desulfurization,demagnetization processes at ambient temperature,a phosphorus concentrate with P2O5 grade and recovery of 28.19%and 78.47%,respectively,is obtained,through which the phosphate rock can be effectively enriched and reclaimed.
