摘要
以大豆油酸化油为原料,经磺化、皂化等单元反应合成了α-磺酸基油酸皂浮选捕收剂,用于四川某中低品位胶磷矿的浮选试验.结果表明,该捕收剂实现了胶磷矿与白云石的有效分离,入选原矿P2O5品位23.80%,MgO质量分数6.54%;获得磷精矿P2O5品位33.88%,回收率85.37%,MgO含量1.50%.
A floatation collector,α-sulfonic acid fatty acid soap,was prepared by steps of sulfonated,saponification with soybean oil as raw material.It was used in the floatation of low-and-middle grade Sichuan phosphate ores.Test results show that the collector realizes the effective separation of phosphate and dolomite,the P2O5 content goes up to 33.88% from 23.80% of run-of mine with a recovery of 85.37%,and the MgO content goes down to 1.50% from 6.54%.
