Typically coal processing is completed with water, which is a very costly and scarce resource requiring stricter permits to operate. The FGX dry coal washing process is proven successful, cost effective, environmentally friendly, and requires only an air quality permit. Coal mining typically results in the recovery of rock that ranges from ...
Acid mine drainage AMD refers to the outflow of acidic water from coal or metal mines, often abandoned ones where ore- or coal mining activities have exposed rocks containing the sulphur-bearing mineral pyrite. Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, this compound forms a dilute acid, which can wash into nearby rivers and ...

The shape of the coal fields also precluded much machine mining, necessitating the use of traditional hand-mining methods. In 1915, only 12.8 of Washington coal was machine mined, compared to the national average of 55. This low level of mechanization resulted in low productivity per man-hour.
