摘要
这是一篇矿物加工工程领域的论文.贵州某碳酸盐型萤石矿,CaF2 含量为 40.56%,矿石成分复杂,碳酸盐类脉石矿物含量高.采用自主研制的新型捕收剂LY-14对其进行浮选实验研究.在磨矿细度-0.074 mm 81.42%,Na2CO3 用量为 1 200 g/t,酸化水玻璃用量 1 200 g/t,单宁用量为 100 g/t,捕收剂LY-14用量为600 g/t条件下,采用"一粗六精一扫"闭路实验流程,获得了CaF2 品位为 96.35%、CaF2 回收率为 91.47%的萤石精矿.
Abstract
This is an essay in the field of mineral processing engineering.There is a 40.56%CaF2 in a Carbonate fluorite ore in Guizhou.The ore composition is complex and the content of carbonate gangue minerals is high.The flotation experiment was carried out with a new collector LY-14 developed by ourselves.Using the closed-circuit test process of"one coarse,six fine and one sweep",under the conditions of grinding fineness of-0.074 mm,content of 81.42%,dosage of Na2CO3 of 1 200 g/t,dosage of acidified sodium silicate of 1 200 g/t,dosage of tannin of 100 g/t and dosage of collector LY-14 of 600 g/t,fluorite concentrate with CaF2 grade of 96.35%and CaF2 recovery of 91.47%was obtained.
