In this article, experiments were conducted under various working conditions in order to recover coal from waste coal slurry by cyclojet flotation. Waste coal slurry with 47.50% ash yielded products having an ash content of 7-17% with 65-80% combustible recoveries. It has been found that results of the cyclojet cell are close to the release curve, and the cyclojet cell can be substituted for the mechanically-agitated conventional cell. Moreover, the total flotation time for the cyclojet cell is 30 seconds and a cell with a capacity of 100 liters can enrich as much as 0.6 tonne of coal (for 5% solid ratio). It has other important advantages, such as having a simple structure, requiring little room, and being easy to operate.
