摘要: 为检验武汉理工大学相关课题组开发的新型阳离子捕收剂MZ-3在磁选铁精矿反浮选中的捕收性能以及消泡行为,以酒钢公司焙烧—弱磁选铁精矿为原料进行了选别和消泡试验。结果表明:①对全铁品位为49.98%的磁选铁精矿进行反浮选脱硅,在pH=7、温度为25 ℃、MZ-3用量为500 g/t、苛性淀粉用量为300 g/t的情况下1次粗选,可获得铁品位为57.01%、铁回收率为74.66%的铁精矿,较好地实现了铁硅分离。②与捕收剂M-302B、醚胺和十二胺相比,MZ-3不仅反浮选精矿产品指标好,而且消泡速度快。因此,MZ-3是一种捕收效果好、易消泡的新型阳离子捕收剂,有利于改善选矿厂的生产指标、提高系统的稳定性。

Abstract: In order to test the froth characteristics and flotation performance of a new cationic collector MZ-3 which was produced by Wuhan University of Technology in the reverse flotation of magnetic concentrate,selection and froth test was conducted on roasting-low intensity magnetic iron concentrate of Jiugang.Results indicated that:①Desilication by reverse flotation on magnetic concentrate with iron grade of 49.98% was conducted at pH=7,temperature of 25 ℃,MZ-3 dosage of 500 g/t,causticity starch dosage of 300 g/t,iron concentrate with iron grade of 57.01% and recovery of 74.66% was obtained via one-stage rough flotation.② Compared with collectors M-302B,amine,and dodecylamine,MZ-3 has characteristics of not only product produced is good,also defoaming fast.Therefore,MZ-3 is a new cationic collector with good collecting and foaming properties,and can improve the efficiency and stability of operations in concentrating mill.
