Dense-medium beneficiation of fine coal revisited

beneficiation of fine coal. Despite its past history, it is still the only process available with the potential to provide the required separation. However, the process needs to be made more ‘practical’ by using larger cyclones, lower pressures and commercially available super-fine magnetite, yet should still give a sharp separation.

Beneficiation Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
