SULFURIC ACID BENEFICIATION OF TITANIFEROUS ORE FOR THE PRODUCTION OF TIO2 |
| 摘要 |
<p>Processes for the efficient and economical beneficiation of titaniferous ore are provided. A unique process for beneficiating ore comprising pretreatment of the ore by oxidation and reduction, followed by acid leaching with sulfuric acid has been developed. The acid used in this process may be recycled, which will thereby increase the efficiency of the process. Preferably the ore treated according to the present invention is ilmenite ore.</p> |
