Studies of Washing Characteristics of Low Grade Coal and

pure coal is 1.2 to 1.7 and for impure coal is 1.7-4.9. In present work, an attempt has been made to study the different characteristics of coal washing by Float-and-Sink test. A design of a washing plant has been made with the help of data collected from this test. The data collected simply shows the washing characteristics of washing of coal from
