Iron is typically obtained from oxide ores such as hematite and magnetite. These ores occur in much larger accumulations, the iron is easier to extract and the metal is not contaminated with sulfur, which reduces its strength. Pyrite used to be an important ore for the production of sulfur and sulfuric acid.
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
