Mineral Processing and Coal Preparation

There is another method to reduce the sulfur content which can be applied even before coal firing in the power stations: the mechanical liberation and subsequent separation of sulfur components by using specialised processing methods. The success of this way of sulfur reduction depends above all on the sulfur distribution in raw coals.

content. For example, coals of 65% carbon may contain 30% oxygen, while coals of 95% carbon may contain only 2-3% oxygen; this is significant because the more oxygen a coal contains, the easier it is to start to burn it, or to achieve its ignition. Sulfur content of coals is seen to be quite variable.
