摘要
昆明地区某中低品位胶磷矿属于海相沉积大型层状磷块岩矿床,采用单一反浮选试验流程,研究其可选性以及最佳药剂制度.试验结果表明:采用原矿P2O5品位为24.46％,MgO含量为5.58％的矿石进行试验,当磨矿细度-0.074 mm达到89.97％,硫酸用量为16.0 kg/t,捕收剂YP6用量为2.0kg/t,磷酸用量1.5 kg/t时,采用一次精选单一反浮选流程,可获得P2O5品位为31.07％,MgO为0.66％的合格磷精矿,P2O5回收率为89.95％的选矿指标.
Abstract
A medium to low-grade phosphate ore in Kunming area belongs to a large layered phosphate rock deposit of marine sedimentation.A single reverse flotation test process was used to study its selectivity and optimal reagent system.The experimental results show that when the raw P2O5 grade is 24.46％and the MgO content is 5.58％,the ore is tested.When the grinding fineness is-0.074 mm and reaches 89.97％,the sulfuric acid dosage is 16.0 kg/t,the YP6 dosage is 2.0 kg/t,and the phosphoric acid dosage is 1.5 kg/t,using a single selection reverse flota-tion process can obtain a qualified phosphorus concentrate with a P2O5 grade of 31.07％,MgO content of 0.66％,and a P2O5 recovery rate of 89.95％.
