摘　　要：通过选矿实验,探析风化胶磷矿选矿的影响因素。研究发现,矿浆浓度、矿浆分散效果及调整剂的添加方式对风化胶磷矿选矿有较大影响。在磨矿细度≤0.038 mm的颗粒占比95.2%,入选矿浆w(固)为19.10%,无机盐L10作为分散剂、碳酸钠和水玻璃作为调整剂添加到磨矿工序条件下,经过一粗一精的正浮选工艺,能够获得w(P_(2)O_(5))31.05%的优质磷精矿。Through the beneficiation experiment,the influencing factors of beneficiation of weathered collophanite are analyzed.It is found that the concentration of slurry,the dispersion effect of slurry and the adding method of adjusting agent have great influence on the beneficiation of weathered collophanite.The results show that when the proportion of particles with grinding fineness≤0.038 mm is 95.2%,the solid content of selected slurry is 19.10%,inorganic salt L10 is used as dispersant,sodium carbonate and water glass are added to grinding process,after a rough and fine positive flotation process,the excellent phosphorus concentrate with w(P_(2)O_(5))of 31.05%can be obtained.
