image: 2 different formats of pyrite crystals. One of the key factors in the formation of cubed pyrite crystals is the presence of sulfur and iron ions in the solution. These ions are necessary for the formation of the mineral, and the ratio of sulfur to iron in the solution can play a role in the size and shape of the resulting crystals.

At Bannockburn, in the Madoc area, a pyrite deposit was discovered below the limonite, which was being mined as an iron ore; this gossan capping of the pyrite was from eight to fifteen feet deep. In the old iron mines near Londonderry, Nova Scotia, the ore was limonite in fissures originally filled with siderite and other carbonates.

An additional reason for removing pyrite prior to burning is conservation of the mineral value. In 1969, over 300 million short tons of coal was burned by electric utilities in the United States. If it is assumed that these coals averaged 2 pct pyrite, 6 million tons of pyrite (53 pct sulfur-47 pct iron) was converted to SO2 and iron compounds.
