Coal Washing Exploration in India dates back to 1900s; though first coking coal washeries in India were installed after independence At present most of the coking coal washeries are owned by Public Sector Companies; whereas most of the non coking coal washeries are owned by Private Sector Even after six decades of coal washing practices
The dense medium cyclone DMC process used in coal beneficiation plants is studied from a control system perspective Employing the dynamic model of the DMC process derived from mass flow balance
The flowsheets to be simulated consist primarily of coal washing units each with a target specific gravity of separation specified for each washing unit The feed is allocated to each washing unit on the basis of separation by size in the screening operations This is a fairly common arrangement for modern coal washing plant flowsheets
According to the annual census of coal preparation plants conducted by Coal Age [] the USA operates 286 coal preparation plants in 12 number is relatively small by comparison to the worldwide fleet which is estimated to be 2 283 plants [] The capacity of the plants can range from less than 200 t/h for small operations to 6 000 t/h or more for large industrial plants
Out of different coal rejects tailings from froth flotation process can be a potential material for the extraction of clean coal due to its fine size availability in the slurry form presence of good carbon values and better liberation properties By adopting chemico physical method and physical method of coal cleaning the overall clean
