对煤中连生体颗粒进行了分类，分析了煤粒可浮性与连生度的关系，并用煤岩定量分析和密度分析的方法考察了不同连生度和密度的颗粒在浮选中的行为。
In this paper, the classification of biogenic particles in coal was studied. The relationship between the floatability of coal particles and the degree of continuous production was analyzed. The behavior of particles with different degrees of continuous biomasses and densities in flotation was investigated by means of quantitative analysis of coal and density analysis .
