Abstract
A separation system and method for separating one or more solid fossil fuels from a contaminated source in a liquid medium, the system including primary separation means and secondary separation means, the primary and secondary separation means being arranged to operate with liquid media of differing specific gravities.
Claims21
A method of separating coal from a contaminated source, the method comprising adding the coal containing contaminated source to a liquid medium, adjusting the specific gravity of the liquid medium carrying the coal containing contaminated source to a first specific gravity by adding water and mineral dirt;
- causing the liquid medium carrying the coal containing contaminated source at the first specific gravity to undergo primary separation;
- adjusting the specific gravity of the liquid medium carrying the coal containing contaminated source from the first separator to a second specific gravity by adding water and mineral dirt, which second specific gravity is different to the first specific gravity;
- causing the liquid medium carrying the coal containing contaminated source at the second specific gravity to then undergo secondary separation.
