有关煤粉(泥)可浮性评定方法的一些看法

Some viewpoints on the evaluation of floatability of coal dust(slime)

论述了用于评定煤泥可浮性的浮选速度试验、分步释放浮选试验和顺序评价试验三种方法,认为前者选择性差,不宜采用,后二者应该在进行大量试验后再予定论;提出了利用浮选精煤灰分临近物相对产率评定煤泥可浮性的新设想。

Discussed was three methods for evaluation of slime floatability,i. e.,flotation rate test,step release flotation test and sequence test; it was considered that the 1st one being low on selectivity and not proposed to be used,the last two will be defined after large volume test work done; a new concept proposed,in that,relative yield of near concentrateash material as the evaluation index.
