Dense-medium beneficiation of fine coal revisited. Spirals were introduced into the South African coal industry in the early 1980s and soon became accepted as the fine coal beneficiation process of choice. Currently, almost every coal processing plant in South Africa employs spirals to beneficiate fine coal.get price

South African coal for local electricity production is among the cheapest in the world. The beneficiation of coal, particularly for export, results in more than 65Mt of coal discards being produced every year.

The quantity of ash in the coal samples designates them as high and moderately high ash content coal (Standard South Africa ISO11760, 2005 E). This is consistent with the fact that all of the coal samples used in this study are byproducts of the coal beneficiation process. The results from XRD analysis of raw materials are showed in Fig. 3.

18.07.2018The first step of Beneficiation is to crush or grind the coal to liberate the coaly matter from ashy matter which can theoretically yield complete liberation. In the case of intergrown texture, finer grinding up to a few micron size is necessary for complete liberation whereas for free dirt ordinary crushing is sufficient (Kumar, D., 1982).
