Processing coal After removing the coal from the ground the miners may send it to a preparation plant near the mining site The plant cleans and processes coal to remove rocks dirt ash sulfur and other unwanted materials This process increases the heating value of the coal
Oct 16 2019 · Coal is defined as having more than 50 percent by weight or 70 percent by volume carbonaceous matter produced by the compaction and hardening of altered plant remainsnamely peat deposits Different varieties of coal arise because of differences in the kinds of plant material coal type degree of coalification coal rank and range of impurities coal grade
The plant uses LCP coalupgrading technology which is a pyrolytic process that employs heat and pressure in an oxygenfree environment to continue the coalification process that occurs naturally in the earth The processed coal by this technology is hydrophobic and transportable which means it will not reabsorb moisture or break up into powder during transportation
