Murray Basin Ilmenite - Realising the Value
Heavy minerals recovered from recently discovered deposits in the Murray Basin are proving to be somewhat more difficult to process into saleable ilmenite products than ilmenites from existing operations. This is due to the nature of the gangue minerals present, the impurities in the valuable minerals and the size distribution of the mineral assemblages. Ilmenite product quality, in particular, can be adversely affected by any of these factors. Over the past two years the authors have been involved in assessing the potential to manufacture ilmenite products from a variety of mineral sand deposits in the Murray Basin. The steps undertaken to define the potential products and develop suitable flowsheets have evolved in parallel to the exploration efforts, in cooperation with companies undertaking exploration in the Murray Basin. A combination of an understanding of detailed mineralogy, application of magnetic fractionation and modification of magnetic susceptibility of the ilmenites has in all cases, been successful in improving ilmenite product quality. The targeting of particular ilmenites to specific downstream processes for TiO2 pigment manufacture is the most challenging aspect of this development.
