Abstract
In this study, we report the experimental results with respect to the beneficiation of fine hardcoal from the Çatalağzı Coal Preparation site tailings containing about 90% (by weight) of −600 µm size particles. These tailings contain 28.41% ash. The coal sample was subjected to a two‐stage concentration process. The underflow product of hydrocyclone under optimized conditions was further processed in Mozley Multi‐Gravity Separator to reduce the ash content of the coal. The results showed that a coal product containing 6.98% ash was obtainable with recovery of 61.73% by this two‐stage concentration process.
