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.

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.
