为了实现对高灰焦粉的有效利用，本文针对高灰焦粉进行了重力分选与浮选降灰的试验研究。结果表明，利用旋流重选柱水介质分选0?5~3 mm 焦粉，可以使其灰分从17％降到10?5％以下，产率为80％左右；利用浮选方法分选-0?5 mm 焦粉，可以使其灰分从20％左右降到10?41％，精焦粉产率可达到80?46％，浮选尾矿灰分为60?92％。研究充分证明了利用重选与浮选降低焦粉灰分的可行性，在此基础上提出了对焦粉进行工业分选的工艺流程。

In order to achieve effective utilization of highGash coke powder,this paper conG ducted experiments of highGash coke powder by using heavy separation and flotation.The results showed that ash content of 0.5~3 mm coke powder can be reduced from 17% to <10.5% after separated in a cyclone column separator and the yield is about 80%.The ash content of -0.5 mm coke powder can be reduced from 20% to 10.41% after separated by flotation methods,with a clean coke powder yield of 80.46% and tailings ash of 60.92%.The study has fully proved the feaG sibility of reducing the ash content of coke powder using heavy separation and flotation methods. Based on these results,a technological process on industrial separation of coke powder has been proposed.
