How fines dry magnetic separation could solve

2021-3-19  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.
