Concept Summary

Coal Washing Process

The coal washing process can be separated to be 3 system as follow : main process,

tailing process, water and treatment process.

- Main ProcessIn the process flowsheet, there are 2 major steps in washing coal :

1. Take out CLAY by SCRUBBER (Scrubber is Rotating Cylinder Drum with Water)

2. Take out STONE by JIG (Jig separate stone out by using water-wave which,

generated by air pulse).

- Tailing ProcessMain purpose of the tailing process is to send 100% of Tailing to tailing sump and pumping

by tailing pump go to settling pond. In the tailing pump.

- Water and Treatment ProcessThis process is balancing circulating a lot of water in entry process, many water nozzles and

water spray heads shall be used for wash coal process. Water from clear water pum

(capacity 400 cu.m/hr ).
