Dry Coal Processing Coal Washing Process

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

CDC

The extraction, transport, and processing of coal produces respirable-sized dust that can be inhaled by miners and cause disabling and potentially fatal lung diseases known as coal workers' pneumoconiosis (CWP, commonly called "black lung") or silicosis. Once contracted, there is no cure for these lung diseases, so prevention is the goal.

Engulfed in a Toxic Cloud: The Effects of Coal Mining On

Feb 01, 2012The continued growth of coal mining has left communities with pervasive and irreparable damage. Until recently, however, the effects of coal on human health have been largely ignored and mining has continued without many appeals for improvement. In both the United States and China, industrial achievements have created a legacy of pollution that is taking a major toll on human health.

Coal Bed Methane Extraction (CBM)

The Coal Bed Methane (CBM) process along with hydraulic fracturing is designed to extract methane from coal seams. The gas wells themselves are the most common pathway for methane migration (leakage). This can lead to high levels of methane in streams, aquifers and eventually drinking water. Methane is 100x worse (on a 20 year time frame) than
