Experimental Study on Flotation of Coarse-grained Ilmenite by New Collector
-
摘要: 以石油化工行业尾料为原料,经酯化合成一种以脂肪酸为主要成分的捕收剂TM,通过粗粒级钛铁矿浮选试验,研究其浮选性能。结果表明:TM药剂和MOH药剂都可以获得TiO2品位≥47%,S品位<0.1%的合格钛精矿。TM捕收剂的用量要比MOH高1000 g/t,但TM不需要使用柴油作为辅助捕收剂。使用TM捕收剂时每吨钛精矿成本比MOH低13.91元。Abstract: A new collector TM with fatty acid as the main component was synthesized from petrochemical tailings by esterification.The flotation performance of TM was studied by flotation of coarse-grained ilmenite.The results show that both TM and MOH reagents can obtain qualified titanium concentrate with the grade of TiO2>47% and S < 0.1%.The amount of TM collector is 1 000 g/t higher than that of MOH,but TM does not need diesel as the auxiliary collector.The cost per ton of titanium concentrate with TM collector is 13.91 yuan lower than that using MOH collector.
