— Magnetic separator is the basic tool used by mineral processing plants to separate ferrous and non-ferrous metals from extracted ore, ensuring high-quality final products. Its works by attracting magnetic particles such as iron, steel and nickel, and then using powerful magnets or electromagnets to separate these particles from other materials.
— What that means in practice depends on the extraction style. If the mineral is paramagnetic – like iron or cobalt – chances are that it's processed using magnetic separation. The mineral is first crushed then funnelled past an electromagnet, the precious material sucked away to safety and the waste product left down below.
