The report states that a 1% reduction in ash content of coal means a reduction of 30 cents in cost of pig iron. One large plant reduces the ash from 7% to 3.5% by cleaning, thus cutting the cost of producing pig iron a dollar or more per ton.

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Electric companies and businesses with power plants burn coal to make the steam that turns turbines and generates electricity. When coal burns, it releases carbon dioxide and other emissions in flue gas, the billowing clouds you see pouring out of smoke stacks. Some …

The termcoalquality is used to distinguish the range of different commercial steam coals that are produced directly byminingor are produced bycoalcleaning. 3 Generally,coalquality for steam coals (i.e.,coalused for electricity generation) refers to differences in heating value and sulfur content ( Table 4.2 ), although other ...

Dec 06, 2017· Lakes, rivers, streams, and drinking water supplies are all heavily impacted bycoalmines andpower plants.Coalis more often associated with billowing smokestacks than it is with water.
