✦ Synopsis

The effect of atmospheric oxidation or weathering on different forms of sulphur in coal has been studied using a coal sample ground to ~63 pm and kept exposed to the atmosphere for up to 228 days. Occasionally, samples were taken from the exposed coal for analysis of total-, sulphate-, pyritic-and organic sulphur. Significant amounts of total-, pyritic-and organic sulphur were reduced up to 106 days of exposure, resulting in a total sulphur content within the permissible limits of utilization. Thus, commercial desulphurization of coal may be possible by using the simple process of atmospheric weathering.

The rationale for magnetic demineralization of coal depends on the paramagnetism of a portion of the coal minerals, their liberation, and their capture by magnetic forces. Pyrite is especially important, being the major form of sulphur in many commercial coals. An experimental separator consisting o
