任何一种选矿方法的应用都取决于矿物组成的物理和物理化学性质,以及有用矿物的结构特性。粗粒嵌佈的矿石,假如其组成中各矿物的比重差異很大时,一般是用重选方法选别。当细粒嵌佈时则普遍采用浮选。在实际条件下,常常须选别那些粗粒嵌佈而各组成的比重差異又很小的矿石。重选方法不能得到金人满意的效果,而在浮选前进行细磨又会使有价矿物过粉碎,造成矿泥中的损失并过量消耗动力。在特殊条件下粗磨,采用浮选和重力浮选就可以大大地改进技术操作过程的指标。有用矿物选矿方面的现代技术政策是趨向阶段选矿流程的应用。全浮选、段间浮选、与磨矿成闭路循环的浮选就
The application of any beneficiation method depends on the physical and physicochemical properties of the mineral composition, as well as the structural characteristics of the useful minerals. Coarse grained ores, if the composition of the minerals in the proportion of large differences, the general is to choose by re-election. Flotation is commonly used when fines are embedded. Under practical conditions, it is often necessary to choose those ores with small differences in specific gravity that are composed of coarse grains and cloths. The re-election method can not get the satisfactory effect of the gold people, and fine grinding before the flotation will overmine the valuable minerals, resulting in the loss of slime and excessive consumption of power. Rough grinding under special conditions, the use of flotation and gravity flotation can greatly improve the technical operation of the indicators. Modern technology policy in the beneficiation of beneficiated minerals is the application of the beneficiation process to the stage. Full flotation, section flotation, and grinding into closed loop flotation
