thorium magnetic separation

The rock contains some environmental hazardous elements such as uranium,thorium, and radon.Magnetic separationand flotation techniques were applied, separately or in combination. Under optimum operating conditions,magnetic separationfollowed by reverse anionic flotation gave a concentrate assaying 0.2% Fe 2 O 3 and about 24% Al 2 O 3 at
