Investigations of Coal Purification by Selective Oil Agglomeration

Abstract

Selective oil agglomeration is used as a physical method to reduce impurities in coal fines. The efficiency of the process depends on many factors. The effects of many operating variables have been examined for different coals and tailings, and the efficiency of the process in coal cleaning has been demonstrated. This study summarizes the work carried out in order to develop coal oil agglomeration as a technique for a cleaner coal-water-fuel slurry production.
