| 摘 要： | 目的在于确定能够有效分散含碳酸盐铁矿石的分散剂。通过有机分散剂种类及用量条件试验,确定了最佳分散剂为NMS-3,其最佳用量为200 g/t。制定了适合选别东鞍山含碳酸盐混合磁选精矿的一次粗选、两次精选、一次扫选的分散浮选工艺流程。闭路试验获得了品位66.37%、回收率75.00%的铁精矿。该浮选指标良好,且工艺流程简单。论文运用DLVO理论对NMS-3分散机理进行了初步探讨,为含碳酸盐铁矿石的有效利用提供理论基础。

| Abstract: | The optimum dispersant that can disperse the iron ore containing carbonate was determined by type and dosage conditional tests of organic dispersants. The optimum dispersant was NM-1, and its optimum dosage was 200g/t. One roughing-two cleaners-one scavenger dispersion flotation process for Dong An Shan mixed magnetic concentrate containing carbonte was proposed. The grade of iron concentrate obtained in close circuit test was 66.37%, and it recovery rate was 75.00%. This separation indexes was ideal, the dispersion flotation processes was simple as well. In this paper, DLVO theory was used to analyze the dispersion mechanism of the dispersant. |
