Abstract

1. A method of treating an ore containing lanthanides and yttrium, including a first stage comprising grinding the ore, followed by a second stage comprising reacting the ground ore with a concentrated aqueous alkali metal hydroxide solution at an elevated temperature, characterised in that grinding is carried out in the presence of a concentrated aqueous alkali metal hydroxide solution at a temperature of up to 100 degrees C.
