Abstract

ABSTRACT: Both a liquid-solid fluidized bed separator (LSFBS) and a dense medium cyclone (DMC) are used for cleaning coal of -1+0.25 mm size. However, a comparison of LSFBS and DMC's performance in separation of difficult-to-separate coal has seldom been reported. Difficult-to-separate coarse coal from the Tangkou plant was processed using LSFBS and DMC. The products with the same ash content were analyzed by the float-sink tests to compare the separation efficiencies. According to the results, the concentrate yield and Ep value obtained by the DMC were 48.85% and 0.045, respectively, while the values obtained by LSFBS were 32.86% and 0.12, respectively. The results showed that DMC was more efficient than LSFBS for separating the Tangkou difficult-to-separate coal with a higher yield and a lower Ep value.
