Coal Washing Encyclopedia
The cleaning process consists of a number of steps that results in a product that is specifically suited to the needs of particular consumers. Among the earliest of these steps is crushing and sizing, two processes that reduce the coal to a form required by the consumer. The next step in coal preparation is a washing or cleaning step.

Liberation is achieved by size reduction of the ROM coal. It is a level-1 process, the product of which is the input to a level-2 plant. In general, the finer the ROM coal is crushed, the greater the liberation of impurities. However, the costs of preparation increase nonlinearly with decreasing desired size. Separation

Beyond the Catch-All Rhetoric: Making Sense of Clean/Dirty 'Clean
Mar 30, 2010Ways to capture CO 2 are either “pre-combustion” or “post-combustion.” One method pipes the carbon dioxide to underground oil wells, where the pressure allows more of the oil to be extracted than otherwise. Another sends the CO 2 to an aquifer or underground to be turned into methane, which can then be returned to the plant to burn. Coal washing

How clean is clean coal? ODI: Think change
Coal is usually more expensive (especially when imported), lower quality (thus less efficient and more polluting); and globally, coal plants run closer to 60% of the time on average. A good case in point is South Africa. For years it has relied on its substantial coal reserves for energy, but the economics of coal have changed rapidly.

Coal preparation plant Wikipedia
The coal delivered from the mine that reports to the coal preparation plant is called run-of-mine, or ROM, coal. This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground
