Research in the Processing and Application of Mineral Sands During the Last Two Decades in Australia

Australia is a leading producer of mineral sands and according to U.S. Bureau of Mines, produced 24, 53 and 64% of world's production of ilmenite, rutile and zircon respectively in 1983. The industry which is mainly export oriented earned in export income about $210 million in 1985. The dominant position which Australia occupies in world produc- tion of mineral sands is also maintained in many areas of research and development work on the processing and application of these minerals. Some of this research which is leading the world has been responsible for setting up industries to produce value-added and high-tech products such as synthetic rutile and partially stabilized zirconia (PSZ). The production of high purity zirconia is due to commence shortly while research in rare earths offers an exciting prospect for future Developments.
