chemical formula for iron ore

Pyrrhotite The mineral pyrrhotite information and pictures

Pyrrhotite is unusual in that it maintains a variable iron content, as reflected in its odd chemical formula.The variability is formed by deficiencies of iron in its chemical structure, which is also responsible for its magnetic properties. Greater deficiency of iron is responsible for stronger attraction to magnetic fields. If the mineral lacks any iron deficiencies, it is no longer
