介绍了选择性絮凝脱硫的研究结果．本法可较好地脱除单体解离的黄铁矿硫，脱硫率可达８０％以上，精煤硫分有较大幅度降低，可由２％左右降到０．７％～０．８％甚至０．５％以下．本法还可同时脱灰，且脱硫脱灰均具有很好的效果．因此，是一种较理想的细粒和极细粒煤泥的分选方法． The research results of selective flocculation desulfurization are introduced. This method can be better removal of monomer dissociated pyrite sulfur, desulfurization rate of up to 80%, a more substantial reduction of sulfur content of coal, from 2% down to 0.7% ~ 0.8 % Or even 0.5% or less. This law can also be at the same time de-ash, and desulfurization ash are with good results. Therefore, it is a better method for sorting fine and very fine slime.
