Abstract

With middlings of TBS underflow from Shanxi serving as sample, recleaning experimental study was conducted in order to improve the recovery of coke. Lab single-cell flotator was used as the main separation device. The ash content of sample was 17.84%, collecting agent dosage and pulp density were separately adjusted to obtain the optimal parameter after cracking to -0.5mm. The experiment results showed that the optimum condition was collecting agent dosage value at 600 g/t, pulp density at 50 g/L, which ensures obtaining clean coal of ash content at 9.89%, recovery at 85.91%. The experimental optimal parameter possessed some guidance for industrial processing.
