How to Remove Pyrite from Coal
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.

Examining Pyrite, Iron and Flint: The Fire Makers
It was quickly replaced during the early Iron Age when flint and steel became the preferred materials. Fire making "kits" of flint and variously shaped steel strikers were still used by a few isolated cultures in the late 1800s. Pyrite survived as a sparking material only into the 16th century, notably in wheel lock firearms, in which a ...
Physiochemical separation of iron ore
The two major aluminum-containing minerals in iron ore are kaolinite (Al 2 (Si 2 O 5 ) (OH) 4) and gibbsite (Al (OH) 3 ). Some progress has been made in using flotation to separate kaolinite from hematite. High levels of phosphorus in iron ore attract a penalty because this makes steel brittle.
