摘要:
为了解决铁矿石阴离子加温反浮选的高能耗问题,利用尿素包裹法分离纯化的棉籽油酸复配的捕收剂进行了常温(15 ℃)反浮选试验. 以齐大山铁矿磁铁精矿为反浮选研究对象, 确定了最佳药剂耗量为:粗选氢氧化钠 0.7 kg/t、淀粉0.4 kg/t、氯化钙0.1 kg/t、捕收剂0.4 kg/t、扫选淀粉0.2 kg/t.开路获得铁精矿品位63.64%、回收率47.88%,并经过闭路试验得到铁精矿品位63.75%、回收率 89.47%的选矿指标. 试验表明纯化后的棉籽油酸常温捕收能力增强,复配16.7%阴离子表面活性剂后捕收能力进一步增强. 为解决常规加温反浮选能耗大,成本高的问题提供了一条可能的途径.
Abstract:
To solve the problem of high energy consumption in heated reverse flotation of iron?鄄ore, flotation tests with purified cotton seed fatty acid by urea adduct method were conducted under normal conditions (15 ℃). Aimed at the reverse flotation of the magnetic concentrate of Qidashan iron ore, the optimum reagent consumption, sodium hydroxide of 0.7 kg/t, starch of 0.4 kg/t, calcium chloride of 0.1 kg/t, collector of 0.4 kg/t, and scavenging starch of 0.2 kg/t ,were gotten. The grade of iron concentrate of 63.64% and recovery rate of 47.88% were obtained in open circuit test. The grade of iron concentrate of 63.55% and recovery rate of 89.47% were obtained in closed circuit test. The test results show that the collecting capacity of purified cotton seed fatty acid under normal conditions is strengthened, which is further enhanced after mixed with an anionic surfactant of 16.7%. It provides a potential way for solving the problem of high energy consumption and high cost in conventional heated reverse flotation.
