钼浮选时入选矿物的粒度大小和磨矿产品质量对浮选指标好坏有决定影响。磨矿不仅影响成本而且也影响选別效果。磨矿和回收率之间有着密切的关系,对处理的矿石维持最佳粒度,就可显著地提高回收率。因此,钼浮选合理粒度是非常重要的。本文根据我国目前钼选矿工艺条件,讨论合理粒度对回收率的影响。 Molybdenum flotation of selected minerals size and grinding product quality flotation indicators have a decisive influence. Grinding affects not only the cost but also the sorting effect. There is a close relationship between grinding and recovery and maintaining the optimum particle size for the treated ore can significantly increase the recovery rate. Therefore, the reasonable size of molybdenum flotation is very important. In this paper, according to the current molybdenum beneficiation process conditions in our country, to discuss the impact of reasonable size on the recovery rate.
