1. Introduction. Coal is regarded as one of the most important non-renewable energy sources. It plays an essential role in power generation, supplying more than 40% of electricity for the world (Xia et al., 2015, Yassin et al., 2022).Before coal burning, a considerable amount of the ash-forming mineral compounds such as carbonates, …

Coal beneficiation is the process of improving the calorific value of the coal by removing the extrane-ous matter or reducing the ash content. This helps the power plants to generate a lesser amount of fly ash, which is harmful to the environment. Coal beneficiation can be done at two stages: 1. Mining stage ² removal of stones and 2.

The process was not used in the Witbank/Middelburg area since the coal from this region was generally considered "non-floating". When spirals were introduced in the early 1980s, the fine coal that would normally have been subjected to froth flotation was sent to the more economical spirals at plants such as Grootegeluk.
