ILMENITE (Iron Titanium Oxide)
Even though rutile is the more common mineral and has a higher percentage of titanium in its formula, it is not concentrated in igneous deposits like ilmenite and is therefore less useful as an ore. However, in sedimentary detrital deposits known as " placers ", both minerals can be concentrated into useable ores.
