摘要:
以碘值135的棉油脂肪酸作为原料通过合成与复配方法获得一种新型磷矿选矿捕收剂；首先将脂肪酸与酰胺药剂进行酰胺化，然后在合成的药剂中复配一定量的烷基酚聚氧乙烯醚表面活性剂.通过气相色谱分析了该脂肪酸的组成，以贵州磷矿为对象，利用常温浮选试验研究了该捕收剂的选矿特性.试验结果表明，碘值135脂肪酸中油酸、亚油酸含量较高，在碳链结构中双键、三键数目多.经过酰胺化和复配15%的表面活性剂烷基酚聚氧乙烯醚，提高了脂肪酸对磷酸盐矿物的浮选效果，在常温浮选过程中，降低了捕收剂的用量.在磨矿细度为\|0.074 mm 79.83%，采用常温正反浮选工艺，获得了五氧化二磷为30.12%精矿，产率为71.20%，回收率为92.90%的选矿指标.
Abstract:
A new collector was prepared through simple amidation using a surfactant OP\|10 compound with fatty acids whiose iodine value is 135 as raw material. To examine flotation performance of the new collector, fatty acid composition was analyzed by gas chromatography and flotation tests with phosphate rock in Wengfu Guizhou in normal temperature were conducted. The test results show that the fatty acids whose iodine value is 135 contain more oleic acid and linolei, selectivity of the fatty acids on phosphate minerals is raised through simple amidation and compounding with a surfactant OP\|10 dosage of synthetic medicament quality of 15%, the dosage of the collector is reduced greatly in the process of phosphate rock flotation in normal temperature. Beneficiation indexes that the phosphorus concentrate grade is 30.12%, the yield is 71.20 % and the recovery rate is 92.90% are obtained with flotation and reverse flotation in the grinding fineness \|0.074 mm 79.83%.
