metallurgy - Students | Britannica Kids | Homework Help

Lower-quality iron ores undergo magnetic separation, in which ore particles pass by magnets and collect around them, leaving nonmagnetic gangue behind. Other ores are separated by flotation. In this process minerals in water stick to a froth of bubbles at the surface while the gangue sinks. This is the most widely used separation process.
