Method of solid fuel beneficiation and transportation to thermoelectric power stations

A method of solid fuel beneficiation and transportation to a thermo-electric power station, comprising the steps of:

• separating minerals constituting a rock mass into a solid fuel using a heavy aqueous liquid,
• placing final beneficiation tailings from said separating step into a worked-out area,
• subsequently regenerating said heavy aqueous liquid from the final beneficiation tailings and returning the heavy aqueous liquid for re-use in said separating step, wherein said regenerating of the heavy aqueous liquid from the final beneficiation tailings includes:
• washing the final beneficiation tailings with a non-aqueous liquid,
• drying the final beneficiation tailings with a subsurface heat source,
• liquifying vapors of said heavy aqueous liquid conning from the final beneficiation tailings,
• distilling effluents left after washing the final beneficiation tailings into aqueous and non-aqueous components using heat released by liquifying the non-aqueous liquid,
• delivering the heavy aqueous liquid, and solid fuel remnants floating in the heavy aqueous liquid, to the thermoelectric power station,
• squeezing the heavy aqueous liquid from the solid fuel remnants,
• washing the solid fuel remnants with water and directing the solid fuel remnants to a combustion process,
• evaporating effluents left after washing the solid fuel remnants using heat released by condensing a working medium of a thermodynamic cycle of the thermo-electric power station,
• combining the effluents left after washing the solid fuel remnants, and the heavy aqueous liquid squeezed from the solid fuel remnants, into a mixture and returning the mixture for re-use in said separating step.
