#0183;#32;A novel, dry process using electrostatics to beneficiate ultrafine coal is being developed by the Coal Preparation Division at the Pittsburgh Energy Technology Center. The historical concept of triboelectricity and its eventual use as a means of charging coal for electrostatic separation
An effective means of dry coal beneficiation is offered by our STEINERT XSS T Xray sorting system based on dual energy xray transmission. This allows ash content to be reduced without the use of water, while specific contaminants such as sulphur can be accurately removed.

However, dry beneficiation of coal has obvious advantages over wet processes. The dry processes for coal are based on the physical properties of coal and its associated mineral matters. Different types of equipment for dry beneficiation have been developed, based on the exploitation of physical properties such as density, size, shape, magnetic susceptibility, and electrical conductivity.
Separation Of Dry Stone Coal In Kragujevac. ALS coal has recently commissioned the latest model of the FGX dry coal separator The technology provides separation of coal from shale or stone without any requirement for water negating the environmental and operational issues g enerated by water usage in conventional coal preparation The FGX process can also be
#0183;#32;Dry separation technology in coal beneficiation has been studied for a long time, and some dry separation techniques have been invented. The air dense medium fluidize bed separation is one potential technique intended to be a substitute for conventional dense medium cyclone/vessel [5], [6], [7] .

The enhanced separation capabilities of the STET system may be a very effective alternative to flotation processes. An economic comparison conducted by an independent mineral processing consulting firm of the triboelectrostatic belt separator versus conventional flotation for barite/quartz separation illustrates the advantages of dry processing for minerals.
