Also, a considerable amount of surfacemined subbituminous coal is lost because of outofseam dilution with mineral matter—an annual loss of as much as 10 million tons was reported for the Arch Coal Black Thunder Mine (which produces about 80 million tons per year). 11 The development of dry coal beneficiation processes designed for these coals could greatly increase recoverable reserves.

beneficiation process of raw coal to a certain percentage ash product, are commonly associated with South African coals. Neardensity material is caused by the presence of finely dispersed mineral matter in the coal that can not be separated from the coal by current liberation methods. The mineral matter referred to is directly linked with the original depositional environment of the coal. The ...

Even better, dry beneficiation is often cheaper than traditional wet processes [24], and is wellsuited to waterscarce regions such as China and South Africa. One example of a recent advance in dry beneficiation is Xray transmission: the use of an Xray linescan sensor to detect and determine whether a material is coal or inorganic material.

1930 to investigate all aspects of coal beneficiation and utilization in South Africa.
