Determination of washability characteristics of Arguvan- Malatya lignite by different washability index methods

摘要

In this study, the washability features of Malatya-Arguvan lignite have been investigated. Experimental studies were carried out with the lignite samples taken from Malatya-Arguvan in Turkey. First, float-sink tests were conducted on -31.5+19, -19+4.75, and -4.75+0.5mm particle size fractions. Then, assessment of the washability features was made by using washability number (W), index of washability (IW), and near-gravity material index (NGMI).
