高磷鲕状赤铁矿选矿工艺研究现状
|
摘要
在分析高磷鲕状赤铁矿矿石性质和资源概况的基础上,较为详细地阐述了传统选矿工艺、磁化焙烧—磁选工艺和深度还原技术在处理高磷鲕状赤铁矿石方面的研究现状,指出传统选矿工艺存在铁精矿品位和回收率低等问题,无法达到高炉冶炼要求,资源浪费严重。磁化焙烧—磁选工艺有利于提高铁精矿品位和回收率,但铁精矿中磷含量仍然较高;深度还原—脱磷或深度还原—富磷工艺等深度还原技术可有效回收高磷鲕状赤铁矿中的铁,是今后高磷鲕状赤铁矿石开发利用的研究方向。
Based on the analysis of high phosphorus oolitic hematite ore properties and resource general situation,the present research status of traditional mineral processing,magnetization roasting-magnetic separation process and deep reduction technology in the treatment of high phosphorus oolitic hematite was elaborated in detail. The traditional mineral process with problems of low iron concentrate grade and recovery rate was pointed out,which could not meet the requirements of blast furnace smelting and resources was seriously wasted. Magnetization roasting-magnetic separation process was eneficial to improve iron concentrate grade and recovery rate,but phosphorus content of iron concentrate was still high. Deep reduction-dephosphorization or deep reduction-riching phosphorus process could effectively recover the iron in high phosphorus oolitic hematite ore,which was the development and utilization direction of high phosphorus oolitic hematite ore research in the future.
