Pyrite
Banded iron formations which usually contain iron as oxides (magnetite, hematite) are much better ores of iron. Sulfur extracted from pyrite is mostly used to make sulfuric acid which has many industrial applications. Because of that it is said that the amount of sulfuric acid produced is a good indicator of country's industrial strength.
