Resumen de New process could unlock untapped US ilmenite supplies
A pilot scheme in the USA, jointly funded by the state government of Minnesota and the University of Minnesota, has delivered pigment-grade titanium dioxide at up to 99.8% purity from large ilmenite deposits that were previously considered unusable.
A pilot scheme has delivered pigment-grade titanium dioxide (TiO2) from the large ilmenite deposits in the US state of Minnesota, which were previously considered unsuitable for commercial use due to the presence of hard-to-remove contaminants.
The Natural Resources Research Institute, part of the University of Minnesota, announced on May 25 that high-quality titanium dioxide had been extracted through a proprietary process which is suitable for commercial application.
The pilot scheme, joint-funded by the Minnesota state government and the University of Minnesota, has delivered pigment-grade titanium dioxide at up to 99.8% purity, processed from 10 tonnes of local ilmenite.
