Klipspruit bulk samples, the enhanced small coal yield of approximately 20% can clearly be seen in Figure 3. It is interesting to note that the coarse coal yields are lowest when it constitutes the greatest proportion of the raw coal feed, whereas the opposite is true of the small coal fraction. It is believed that this can be explained by the fact
