Laboratory test showed that: In consideration of slump, the optimization content of the fly ash was around 30% or more than 30%.

试验结果显示：从坍落度方面考虑，粉煤灰的掺量应该在30%左右或大于30%为最佳。

The test results show that the concentrate with ash content lower than 12.00% can be separated from high ash middling using this process.

试验结果表明，该工艺可以从高灰中煤中分选出灰分低于12．00％的精煤。
