FGX technology is an innovative, efficient, coal preparation process using air. 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.
