PROCESS FOR THE RECOVERY OF TITANIUM IN MIXED CHLORIDE MEDIA |
摘要 |
<p>A process for leaching a value metal from a titanium-bearing ore material comprising the step of leaching the ore material at atmospheric pressure wit h a lixiviant comprising a chloride and hydrochloric acid is disclosed. The leaching conditions are such that titanium is leached and remains in solutio n. The temperature is maintained at less that 85~C, and the concentration of hydrochloric acid is preferably less than 20% (mass ratio). The preferred chloride is magnesium chloride. The lixiviant may contain oxidant e.g. sodiu m chlorate or chlorine.</p> |
