一、浮选药剂的作用和分类 我们知道,要使矿物通过浮选方法达到有效的分离,其基本条件之一是在被分离的矿物之间具有足够大的可浮性的差异。这种差异可以是各种矿物本身之间所具备的。但是在浮选实践中,几乎毫无例外地需要加入一些无机的或有机的化学药剂以人为地扩大矿物之间的可浮性差异,使浮选成为可能或更加有效,这种化学药剂,即被称之为浮选药剂。 可以说,正是由于浮选药剂的应用,才使浮选法成为一个重要的选矿方法而问世。自从全油浮选开创了浮选方法以来,人们经过大量实践,在药剂的原料、种类、加工合
I. FUNCTION AND CLASSIFICATION OF Flotation Agents We know that one of the basic conditions for achieving effective separation of minerals by flotation is that they have a sufficiently large flotability difference between the minerals being separated. This difference can be between the various minerals themselves. However, in the practice of flotation, it is almost without exception necessary to add inorganic or organic chemical agents to artificially increase the floatability difference between minerals, making it possible or more effective for flotation, that is, It is called flotation reagent. It can be said that it is because of the application of flotation reagents, the flotation method has become an important beneficiation method came out. Since the flotation process of all-oil flotation has been started, people after a lot of practice, in the pharmaceutical raw materials, types, processing
