一、粒浮(抬浮)选鑛法的原理和操作粒浮选鑛法是同时利用浮游和重力法以联合进行选别的方法。苏联原称为浮游一重力选法或摇床浮选,我们初译为“抬浮”,后改为粒浮,以区别于通常的泡沫浮选。依照苏联专家B.M.阿拉什凯维奇的解释:粒浮是早先的表膜浮选予以现代化装备的实现。因此,它的理论依据就是利用鑛石表面的物理化学性状在与极性液体(例如水)或非极性液体(例如油类)的接触面间所显示的差异,使疏水性鑛物(如硫化鑛)易为油膜所包覆,随气泡浮出液面;使亲水性鑛物(如石英)因易被水濡湿而沉浸于底部,对于所要选别的鑛物(疏水性),通常再加以化学药剂(例如黄药,松根油类)的作用和机械搅动,使疏水性鑛物与更多的空气相接触,在其 First, the grainy (lift) principle and operation of beneficiation method Granulite beneficiation method is the use of both floating and gravitational method to jointly select the method. Originally known as the Soviet Union floating weight gravity method or shaker flotation, we first translated as “floating”, later changed to grainy, to distinguish the usual froth flotation. According to the Soviet expert B.M. Alaskiewicz’s explanation: Particle float is the realization of the modernization of the previous membrane flotation. Therefore, its theoretical basis is to make use of the difference between the physical and chemical properties of the ore surface and the contact surface with a polar liquid (such as water) or a non-polar liquid (such as oil), so that hydrophobic minerals Mine) is easily covered with oil film, with the bubble surfaced; make hydrophilic minerals (such as quartz) because of easy to get wet and immersed in the bottom, for the minerals to be selected (hydrophobic), usually with chemical The action of the agent (eg xanthate, pine root oil) and mechanical agitation bring the hydrophobic mineral into contact with more air,
