Application of dry LIMS is often employed in the separation of highly magnetic VHMs and/or in eliminating highly magnetic gangue or mineral impurities and tramp iron. More so, dry LIMS is usually employed in separating coarser HM sands that are composed of highly magnetic HM particles. This process is basically known as cobbing [9,49].
