Leucoxene is an alteration product of titanium-bearing minerals. Leucoxene is not a mineral because it lacks defined crystal structure and its chemical composition is far too variable to be expressed as a chemical formula. It is an alteration product of minerals like ilmenite, rutile, and titanite (sphene).
Leucoxene is formed in nature through the weathering of ilmenite over an extensive period of time. This weathering removes ilemenite's iron content and increases its titanium content. Leucoxene grains are often found in mineral sand but is not regarded as a mineral

Mining Heavy Minerals: Excavators remove heavy mineral sands at the Concord Mine in south-central Virginia. Weakly consolidated sands containing about 4% heavy minerals are excavated and processed to remove ilmenite, leucoxene, rutile, and zircon. The sands were weathered and eroded from an anorthocite exposure a short distance away.
Titanium occurs primarily in the minerals anatase, brookite, ilmenite, leucoxene, perovskite, rutile, and sphene. Of these minerals, only ilmenite, leucoxene, and rutile have significant economic importance. As a metal, titanium is well known for corrosion resistance and for its high strength-to-weight ratio.

Ilmenite is commonly recognized in altered igneous rocks by the presence of a white alteration product, the pseudo-mineral leucoxene. Often ilmenites are rimmed with leucoxene, which allows ilmenite to be distinguished from magnetite and other iron-titanium oxides. The example shown in the image at right is typical of leucoxene-rimmed ilmenite.
Leucoxene is formed in nature through the weathering of ilmenite over an extensive period of time. This weathering removes ilemenite's iron content and increases its titanium content. Leucoxene grains are often found in mineral sand but is not regarded as a mineral

It is found as an accessory mineral in many rocks, particularly gabbro and anorthosite. It can be found as a heavy mineral in detrital sediments, although it does alter readily to a mixture of white to yellow titanium oxides known collectively as leucoxene.
