Washability - an overview | ScienceDirect Topics
网页Washability refers to the process of cleaning mined coal to reduce its mineral contents before it is sold. This process involves performing tests to predict the effectiveness of coal cleaning by generating various gravity samples that are analyzed for their heating values, ash and sulfur contents, among other factors.
