摘要:
为了考查几种捕收剂用于磷矿浮选脱硅的效果，以云南海口磷矿擦洗尾矿为试验样品，进行了正浮选和反浮选脱硅对比试验.结果表明，对于硅质矿物受钙镁离子污染活化的细粒含硅磷矿，采用常规脂肪酸和胺类捕收剂，无论是正浮选或反浮选脱硅，其选择性都不好.通过对脂肪酸进行复配改性，降低捕收剂中脂肪酸组分的含量，并利用混合药剂的协同作用，可以明显改善捕收剂浮选磷酸盐矿物的选择性，提高正浮选脱硅的选矿效率.
Abstract:
To evaluate the effect of several collectors on desilication flotation of phosphate ore,the contrast tests of positive and reverse flotation were carried out taking phosphate scrub tailings in Yunnan Haikou as samples.The results from positive and reverse flotation using conventional fatty acid and amine as collectors show that the selectivity of fine particle activated by calcium and magnesium ions is poor.Modifying the composition of collector by mixing different surfactants and decreasing the fatty acid amount in the collector can have a synergistic advantage over the use of a single fatty acid.As a result the selectivity of phosphate flotation or beneficiation efficiency of desilication increased obviously.
