摘 要: | 目前国内部分铁矿采场都有一定量的排岩,有的采场排岩当做废石处理,而该废石亦含有部分可选性较好的磁性铁矿物,对国内某铁矿采场的排岩进行了阶段干选、干选精矿磨选试验研究,结果表明在干选抛弃大量的干选尾矿后,获得的干选精矿经过磨矿弱磁选试验获得了质量较好的铁精矿。

Beneficiation Research on Waste Rocks Containing Iron Ores of a Iron Mine |

Abstract: | At present,some of iron ore stopes at domestic have a certain amount of waste rocks.Some rocks are treated as waste rock,but the waste rock also contains magnetic iron minerals with good dressing ability.Experiments on waste rocks from an Iron Mine at domestic are made through the process of stage dry magnetic separation and dry concentrate separation after grinding.The results show that after a large number of waste rocks tailings are cast by dry magnetic separation,and dry concentrates are treated by low intensity magnetic separation after grinding,high-quality iron concentrates are achieved. |
