USGS Bulletin 1823 - Determination of Forms of Sulfur in Coal

The sample may contain an iron-bearing mineral that is incompletely dissolved in hydrochloric acid; thus, the iron appears as pyrite iron in a subsequent digestion with nitric acid. Iron-bearing minerals likely to occur in coal include siderite, hematite, marcasite, and goethite (Elliot, 1981).

Oxidation of pyrite in coal to magnetite - ScienceDirect

When bituminous coal is heated in an inert atmosphere (He) containing small amounts of oxygen at 393–455 °C, pyrite (FeS 2) in coal is partially converted to magnetite (Fe 3 0 4).The maximum amount of Fe 3 0 4 formed during the time of heating corresponds to 5–20% of the total pyrite present, depending on the coal sample. The magnetite forms as an outer crust on the pyrite grains.
