Answer
As the crushed ore is distributed over the drum, the magnetic ore, also known as ferrous material, is attracted to the magnet. This allows the magnetic particles to be held by the drum.

Answer
The non-magnetic waste material falls off the drum due to gravity as it rotates, thus separating it from the magnetic particles.
