Process for treating zircon |
| abstract |
A process for the treating of zircon to remove a coating which contains iron from the surface of individual grains to make them move amenable to electrostatic and magnetic separation, wherein the method comprises cooling the zircon grains with a strong basic reagent, calcining the coated grains and treating the calcined grains to remove the calcined impurities. |
