中文摘要:

      通过L27(9×39)混合水平正交试验确定天青石矿浮选的捕收剂和优化的工艺条件,具有试验次数少、考察因素充分的优点。正交试验的极差分析结果显示,捕收剂种类和捕收剂浓度对回收率的影响最大,原矿来源和捕收剂种类对精矿品位的影响最大。通过试验选择出对天青石矿捕收效果好的捕收剂,即十二烷基硫酸钠、十六烷基三甲基溴化铵和单烷基磷酸酯,初步得到一些关键工艺条件:浮选时间(10～15 min)、叶轮转速(2 340 r/min)、矿浆中固体质量分数(25%)和药剂与矿样的质量比(2∶1000)。

英文摘要:

      Collectors and optimum processing condition of celestite flotation were determined by L27(9×39) mixed levels orthogonal experiment,which has the advantages of less test times and full investigation factors.The range analysis of orthogonal experiment shows that species and concentration of collector have the most influential effect on recovery rate,and raw ore source and species of collector have the most influential effect on concentrate grade.The high efficiency collectors of celestite were selected,namely...
