过滤作为一种从悬浮液中排除液体的方法已是一种古老的选矿技术。采用适当的过滤介质阻留弥散相(主要是固体)一般不存在什么困难。很早以前就认识到使用滤布、滤板和其它疏松介质的可能性,至今对用于不同条件下的过滤介质仍在继续进行研究。按需求还研制了相应的过滤机,且目前已达到相当高的技术水平。 Filtration has been an ancient beneficiation technique as a way of removing liquids from a suspension. There is generally no difficulty in using a suitable filter medium to retain the dispersed phase (mostly solids). The possibility of using filter cloths, filter plates and other loose media has long been recognized, and so far, the use of filter media under different conditions has continued. According to demand also developed the corresponding filter, and has reached a very high level of technology.
