this reason, dense-medium beneficiation of fine coal was reconsidered. Motivation In past years, much of South Africa's export coal was produced from the No. 2 Seam. The fine fraction from this seam is relatively easy to beneficiate in spirals. In future years, however, a large proportion of coal will be mined from the No. 4 Seam.
