摘要
通过对大冶铁矿铜铁矿石进行系统的助磨剂研究 ,筛选出多种有效助磨剂 :DY 1 # 、DY 2 # 、多聚磷酸钠、AMPC、马来酐、木质素磺酸盐、聚丙烯酸钠。其中开发研究的DY系列助磨剂助磨效果最好。文中介绍了当磨机处理能力不变时 ,DY 1 # 、DY 2 # 助磨剂能分别使原生矿、混合矿产品中 - 2 0 0目粒级的产率相应提高 7 8个百分点和 4 6个百分点 ;当磨矿细度保持不变时 ,磨机处理能力相应提高 4 6个百分点和 5个百分点。助磨剂的加入对后续浮选、磁选和脱水作业无不良影响。
Through a systematic investigation on grinding aids for copper iron ores of Daye Iron Mine,several efficient grinding aids were screened out,such as DY 1 #,DY 2 #,poly sulphonate sodium,AMPC,maleic anhydride,lignosulfonate,polyacrylate sodium,of which DY series grinding aids have the best effect.At an unchanged mill throughput,DY 1 # and DY 2 # grinding aids can raise the weight percent of -200 mesh fraction of the products by 7.8% for the primary ore and 4.6% for the mixed ore respectively.And at an unchanged grind,the mill throughput can be improved by 4.6% and 5% respectively.The addition of grinding aids has found no adverse effects on the subsquent flotatoin,magnetic separatoin and dewatering processes.
