Sequential microwave roasting and magnetic separation

We investigated a method for removal of Fe and Ti impurities to improve the grade of pyrophyllite ore using sequential microwave roasting and magnetic separation. Pyrophyllite ore from the Wando mine (South Korea) contains Fe impurities, such as pyrite and hematite, and Ti impurities, such as rutile and Ti-oxides.
