Towards Understanding Phosphorus Distribution In Coal:

Towards Understanding Phosphorus Distribution In Coal:

Current density beneficiation does not always reduce phosphorus contents from product coal to meet the imposed tolerances. This is because phosphorus can occur as small ( 20 ), discrete inorganic minerals within the coal particles as described by Ward (2016) and so can occur across different size fractions and densities (Partridge et al., 1992). A number of mine sites have observed a concentration.
