Introduction. India has proven reserves of coal amounting to ∼126 billion tonnes out of which ∼18 billion tonnes is metallurgical or coking coal, ∼107 billion tonnes is thermal coal, and ∼1 billion tonnes is tertiary coal (Venugopal et al., 2016).Coal preparation or washing in India started in the early 1950s for metallurgical coal (Venugopal et al., 2016).

Thus, three products are produced by this process. Clean coal is supplied to steel plants, the middlings to thermal power stations, and the rejects are usually dumped near the washery or utilized for power generation. Summing up, raw coal is usually crushed to 15 mm and then screened into three fractions 1525 mm, mm and mm.

The recovery of clean coal from washery rejects is of great significance for protecting China's scarce coking coal resources. The main purpose of this work was to design a deep process that can maximize the recovery of clean coal from a coking coal washery rejects with about 50% ash and test the technical feasibility of the process.
