| 摘 要： | 采用东北大学新合成的两性捕收剂DA-1，对鞍钢齐大山选矿厂混磁精矿进行了反浮选条件试验，确定的适宜的粗选作业条件为浮选温度20 ℃，矿浆pH=11.5，捕收剂DA-1用量600 g/t，抑制剂糊化淀粉用量为600 g/t；在适宜的工艺技术条件下，采用1粗2扫、中矿顺序返回的闭路流程处理铁品位为42.92%的混磁精矿，获得了铁品位为67.31%，回收率为87.90%的精矿产品。

| Abstract: | An amphiprotic collector DA-1 synthesized by Northeastern University was used to float the mixed magnetic concentrate of Qidashan dressing plant in Anshan Iron and Steel Company.The optimal rougher floatation condition is flotation temperature 20℃,pH of pulp 11.5,dosage of DA-1 600 g/t,and dosage of depressor gelatinization starch 600 g/t.At appropriate technical conditions,a closed circuit flotation flowsheet of single-stage roughing,two-stage scavenging,and middles returning was adopted to handle a mixed magnetic concentrate with Fe 42.92%.A concentrate of Fe concentrate grade 67.31% and recovery 87.90% was obtained. |
