The leaching conditions are such that titanium is leached and remains in solution. 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. sodium chlorate or chlorine.
