摘要:
以司家营铁矿磁选精矿为研究对象,采用新型改性脂肪酸类捕收剂,在浮选温度为25 ℃下,通过条件试验确定最佳药剂用量(粗选氢氧化钠 1 500 g/t,淀粉650 g/t,石灰 550 g/t,捕收剂 450 g/t;精选石灰 200 g/t,捕收剂 450 g/t),进行一粗一精开路浮选得到精矿品位66.56%,回收率为70.64%,并经过闭路流程获得精矿品位65.79%,回收率为83.01%,尾矿品位13.58%的选矿指标.试验表明,该新型捕收剂选择性强,常温下水溶性好,解决了常规加温浮选能耗大、成本高的问题.
Abstract:
Taking magnetic concentrate of Sijiaying iron ore as object of study, and chosing new modified fatty acid collector,the best reagents consumption was decided based on the conditional experiment at the temperature of 25 ℃(rougher: NaOH 1500 g/t,depressant 650 g/t,CaO 550 g/t,collector 450 g/t; cleaner: CaO 200 g/t,collector 450 g/t). The concentrate grade of 66.56% with the recovery rate of 70.64% was obtained at open circuit. The concentrates grade of 65.79% with the recovery rate of 83.01% and the tails grade of 13.58% were gained at experiment of closed circuit. The experimental results indicate that the new collector has excellent selectivity and good watersolubility, can help to solve the problems of high energy consumption and high cost in regular hightemperature flotation.
