Nevertheless, ceramic industry customers in Europe and Asia have advised that Coburn zircon can be blended with premium grade material for glazing of tiles, the principal ceramic use.

(indicative value for iron oxide, I'm inferring values are known for other Fe compound)
The radiation hazard level of Coburn’s zircon, expressed by its uranium and thorium (U+Th) content of between 320-450 parts per million , is quite low and compares favourably with the accepted international limit of 500 parts per million.

Leucoxene is an altered form of ilmenite, in which the iron (Fe) has been preferentially leached out by acid groundwater , increasing the TiO2 content. The leucoxene from the Coburn Project is unusually altered and high in TiO2 and, for this reason, can command a higher price and
