As with other higher rank coal, sink and float experiments show the washing possibilities of waste coal. However, waste coal is easy to clean, which mainly depends on the content of near-gravity materials at specific gravities (Khoonthiwong et al., 2020, Liu et al., 2016). Usually, the coal hydrophobicity is reflected by the contact angle and ...
