摘要: 用实验室合成的一种含羟基、羧基及硫酸酯基团的阴离子捕收剂LSMFS,与一种廉价脂肪酸皂组合复配出一种新型碳酸盐磷矿捕收剂LG-01,以P2O5品位为25.31%的贵州某碳酸盐磷矿为对象进行了反浮选效果研究,并用IR分析法探讨了组合捕收剂的主要成分分别与碳酸盐磷矿表面的作用机理。试验表明,组合捕收剂LG-01是一种来源广泛、价格低廉、对温度不敏感的低毒、高效捕收剂,1次粗选即可获得P2O5品位为34.79%、回收率为90.64%、含MgO 1.01%的优质磷精矿。

Abstract: Anionic collector LSMFS containing hydroxyl, carboxyl and sulfate groups was synthesized mixed with a cheap fatty acid soap to be a new carbonate phosphate collector LG-01.A carbonate phosphate from Guizhou with P2O5 grade 25.31% was taken as the research object and reverse-flotation tests on the ore was carried out.And then the main component of combined collector LG-01 onto carbonate phosphate surface was respectively discussed by IR.Laboratory tests show that the combined collector LG-01 is a low toxicity and efficient collector which not only has wide variety of sources, low cost, but also is not sensitive to temperature.The high-quality phosphorus concentrate with P2O5 grade 34.79%, MgO 1.01% and recovery 90.64% was obtained through single flotation.
