Mar 10, 2014· Mineral Mining and Processing Effluent Guidelines. EPA promulgated the Mineral Mining and Processing Effluent Guidelines and Standards ( 40 CFR Part 436) in 1975, and amended the regulation in 1976, 1977, 1978, and 1979. The regulation covers wastewater discharges from mine drainage, mineral processing operations and stormwater runoff.
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.

Jets were applied to wash down part of a hillside for sluicing. The stream could be so strong that it would reflect a crowbar swung at it. When gravity could not be used for sluicing, a lift could be applied; it used pressurized water, introduced at the bottom, to suck up a mixture of water and gravel. This could also be an alternative to shaft mining as seen on picture 2.
