高品位矿石储量的衰竭和市场要求提高产品质量的压力的不断增加,迫使生产厂家重新审查其工艺流程和评价可替代现有的或补充性的选矿方法,要求更高质量的球团矿则意味着SiO_2含量需从2.0%降至1.0%以下。反浮选柱(硅从铁精矿中浮选出去)已被证明是降低精矿中硅含量的一种经济有效的方法。实验室和工业研究均证明使用浮选柱带来了可观的冶金和经济效益。卓越的选矿指标和低投资以及低运转费用使柱浮选机在选矿厂被广泛应用,在进行铁矿石选矿时,其冲洗泡沫的能力被证明可以获得低含硅量,同时可以把铁的损失减小到最低程度。新近的成本比较显示,安装一
The depletion of high-grade ore reserves and the increasing pressure from the market for higher product quality have forced manufacturers to reexamine their processes and evaluations to replace existing or complementary beneficiation methods, requiring higher quality pellets to mean The SiO 2 content needs to be reduced from 2.0% to 1.0%. Reverse flotation columns (flotation of silicon from iron concentrates) have proven to be a cost-effective method of reducing the silicon content in the concentrate. Both laboratory and industrial studies have demonstrated the considerable metallurgical and economic benefits of using flotation columns. Outstanding beneficiation indicators and low investment and low operating costs make column flotation machines widely used at mineral processing plants. When iron ore beneficiation is carried out, its ability to flush foams proves to be of low silicon content, Losses reduced to a minimum. Recent cost comparison shows that installing one
