Technical Note Effect Of Conditioning On The

Amount of near-density material present in the beneficiation process depends on the percentage ash, in the clean coal product, required. As the ash distribution is the controlling factor on near-density material, any external factor that effects the ash distribution will affect the coal’s washability characteristics.Size reduction of the coal. Coal beneficiation based on surface activity differences also require the coal to be small to be able to present sufficient surface for the chemicals to work. The very fine coal particle sizes required for these processes make the resulting cleaner coal unsuitable for the SasolLurgi gasifiers. Hence, methods need to be.

Aspects by physical and chemical beneficiation of high ash and sulfur containing coal. Physical beneficiation of coal is not very effective in separation of the finely dispersed minerals, whereas chemical beneficiation uses expensive reagents and leads to generation of large amount of wastewater which needs to be purified before discharge.Coal components have properties adding to the value of the product, like coking properties. It is therefore of economic importance to maximize the amount of valuable coal recovered from raw coal [3]. This coal can be of a low overall grade requiring beneficiation [2, 8], but even this may not improve the grade, because of the narrow layers.
