Coal mining typically results in the recovery of rock that ranges from small to very large quantities depending on geological characteristics. In some areas of the United States, large quantities of rock are being extracted in order to recover the coal, reportedly resulting in 60%-70% of the raw material being rejected as waste. The haulage, processing, and storage of the rock represent significant energy inefficiency and have a negative environmental impact. The process of removing unwanted rock from run-of-mine coal is referred to as deshaling which normally involves a high-density separation in a gravity-based process.

FGX dry coal processing is an effective deshaling technology developed by Tangshan Shenzhou Manufacturing, Co. Ltd (TSM). The FGX compound dry cleaning separator provides an efficient, dry and gravity-based separation by integrating two separation mechanisms including autogenous fluidized bed and conventional table separator  As a completely dry process, the FGX technology provides a coal preparation method that does not involve the use of water and its associated water treatment processes, which means Saving Water Costs.  Since we propose to do FGX deshaling at mine sites prior to ROM coal being transported to prep plants, considering the skyrocketing diesel price, as shown in the figure below, using FGX also results in Saving Transportation Costs.

By using an FGX process, a certain amount of rock is rejected even before it enters coal prep plants.This means Saving Processing Costs because prep plants do not have to wash unnecessary materials. Actually, in this case the feed to prep plants is deshaled product which is much cleaner than the original ROM coal, therefore, prep plant productivity is improved as well.
