自本世纪初矿物工业出现浮选以来,浮选已成为一种用得最广的选别方法。由于浮选的参数多,产生的现象复杂,所以至今仍没有一种设计得特别合理,令人满意的浮选机。迄今为止,人们就浮选的化学方面,尤其是捕收剂的选择研究得很多,而对浮选机研究得不够。尽管如此,国外仍出现了不少浮选 Flotation has become one of the most widely used selection methods since the flotation in the mineral industry at the beginning of this century. Due to the large number of flotation parameters and the complex phenomena that occur, no flotation machine has been designed so far to be particularly reasonable and satisfactory. So far, there has been a lot of research on the chemical aspects of flotation, especially the choice of collectors, but not enough on flotation machines. In spite of this, there are still many overseas flotations
