摘要

Beneficiation of ilmenite through structural alteration produced by thermal treatment followed by acid leaching has been attempted. The paper discusses the changes in the structure of ilmenite when heated to different temperatures. The altered structures have been examined for their amenability to acid leaching to selectively dissolve iron values. Pseudo-brookite structure formed at 1300 K from ilmenite was found to respond favourably to leaching with 20 wt% HCl. The TiO_2 content of the product amounted to 92.48 wt%.
