中文摘要:大红山铁矿所生产的50%品级铁精矿现状为直接落地销售,为使经济效益最大化,对50%品级铁精矿进行提质降硅,作为铁精矿并入总精矿再进行销售;对50%品级铁精矿采用“一粗一精一扫”的闭路正浮选流程,最终所得精矿铁品位达到57.79%,硅品位由14.22%降低至8.09%,可作为铁精矿并入总精矿再进行销售。

Experimental study on upgrading of 50% grade iron concentrate in Dahongshan
Abstract:The current status of 50% grade iron concentrate produced by Dahongshan is directly sold. In order to maximize economic benefits, 50% grade iron concentrate is upgraded and silicon is reduced, and iron concentrate is integrated into total concentrate. Sales; 50% grade iron concentrate adopts “one coarse and one fine sweep” closed-circuit positive flotation process, the final refined iron grade reaches 57.79%, silicon grade is reduced from 14.22% to 8.09%, which can be used as iron fine The mine is incorporated into the total concentrate and then sold.
