大家都知道,粗粒嵌布结构的和选鑛鑛物比重相差悬殊的鑛石,通常都用重力选鑛法来选别。对若干类型细粒嵌布特徵的鑛石必须将原鑛大大磨细。此时最常用的选鑛方法就是浮选。有些鑛石虽然是粗粒嵌布的,然而鑛物间之比重却极为相近。因此根据选鑛过程的特点,无论是重选,或是孚选都不能有效地选别这种类型的鑛石。因此,浮选和重选法不适於选别粗粒嵌布结构的鑛物和比重极相近以及高比重的鑛物,这就迫使我们探索新的、同时又是最完善的选鑛方法。当鑛石和需要再加工的粗精鑛其鑛物组成很复杂时,这
As we all know, coarse grained cloth and ore dressing mineral composition of the difference between the disproportionate ore, gravity sorting method are usually used to sort. The ores of several types of fine-grained ridges must be ground very finely. At this point the most commonly used mineral processing method is flotation. Although some ores are coarse-grained, the proportions of minerals are very similar. Therefore, depending on the characteristics of the beneficiation process, neither the re-election nor the selection of fu is effective in the selection of this type of ore. Therefore, the flotation and re-election laws are not suitable for the selection of coarse-grained embedded minerals and minerals with similar specific gravity and high specific gravity, forcing us to explore new and perfect mineral processing methods. This is the case when the ore and the crude concentrate that needs reprocessing have complex mineral compositions
