Process for the removal of iron contamination from zirconiferous material

摘要

A process for the removal of iron oxide coatings from zirconiferous material includes a first step of heat treating the zirconiferous material at a temperature, not greater than 450 DEG C and for a period sufficient to activate the coatings for enhanced ease of removal. The product of the first step is thereafter subjected to a leach and/or attritioning treatment.
