| 摘 要： | 对东鞍山含碳酸盐铁矿石的工艺矿物学进行了研究, 提出了处理含碳酸盐铁矿石的分步浮选工艺流程:第一步, 在中性环境中采用正浮选分离出碳酸盐; 第二步, 在强碱性环境中采用反浮选分选赤铁矿。工业生产实践表明, 分步浮选取得了较好的技术经济指标, 对同类选矿厂具有较好的借鉴作用。

| Abstract: | Based on the study on process mineralogy of carbonate-containing refractory iron ore in Donganshan Iron Mine, stepped flotation process was proposed for treating such kind of ore. At the first stage, siderite was separated by direct flotation with a neutral media, and at second stage, hematite could be separated by reverse flotation in a strong alkaline solution. The production practice showed a good performance was achieved by such stepped flotation process, which can be of reference for processing similar iron ore. |
