摘要
在磷灰石浮选过程中传统捕收剂存在矿浆需加温及用量过多等问题。通过合成一种新型磷灰石常温捕收剂DYX,并以此为捕收剂对磷灰石单矿物进行了浮选试验研究。试验结果表明,在矿浆温度为26℃,矿浆p H值为10.0,捕收剂DYX用量为400 g/t、抑制剂水玻璃用量400 g/t的条件下,磷灰石的浮选回收率达到94.58%,说明该新合成的捕收剂具有常温下捕收作用能力强、用量少的特点。动电位和红外光谱分析结果表明,该捕收剂在磷灰石表面以氢键和化学键合吸附为主。
There still exist problems of pulp need to be heated, poor adaptability and too large the dosage of collector in apatite ore flotation. Thus, a new collector DYX had been prepared in order to solve the problems. And flotation experiments of single apatite was conducted. At the condition of temperature 26℃, pH 10. 0, and DYX dosage 400 g/t, sodium silicate dosage 400 g/t, apatite recovery was 94. 58%. The results show that the amount of DYX used is less. And the collector had strong collecting ability at temperate of 26℃. Mechanism Analysis according to the resuits of FFIR and zeta potential show that reactions between molecules of DYX, and the surface of the apatite are mainly hydrogen bond and chemical bonding adsorption.
