当前国内外铁矿石选矿普遍发展趋势是实现高品化精矿,精矿品位一般都要求65％TFe以上。为了适应形势的发展和生产的需要,马钢桃冲铁矿最近进行了一次旨在获得高品位精矿的选矿试验。试验发现,无论采用什么选矿方法以至复杂的联合流程处理,精矿TFe品位都达不到65％以上。这就提出了一个问题:精矿品位究竟能够达到多高,应该多高合理,也就是说选矿指标合理界限究竟怎样。现仪就试验中的矿石性质特征及其与选别结果的关系的研究和对实际选别指标的分析,谈谈该矿石的选矿指标合理界限问题,供贯彻精料方针制定
At present, the general trend of iron ore beneficiation at home and abroad is to achieve high-quality concentrate. Concentrate grades generally require 65% TFe or more. In order to meet the needs of the development of the situation and production, Masteel recently conducted an ore dressing test aimed at obtaining high-grade concentrates. The test found that, no matter what the beneficiation method and complex joint process, concentrate TFe grade are less than 65%. This raises the question: how high the concentrate grade can be achieved, and how high it should be, that is, what is the reasonable limit of beneficiation? Present instrument on the characteristics of the ore in the test and its relationship with the results of the election and the actual selection of the index analysis, to talk about the ore beneficiation indicators reasonable boundaries for the implementation of fine materials guideline
