Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them. The ore is first ground into fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt. Froth Flotation Method:

Han et al. achieved a zinc recovery of 92.6% by reduction roasting with acid leaching, while the iron remained in the slag and could be recovered from the residue after magnetic separation. Most zinc-bearing secondary resources contain zinc in the form of zinc ferrite, which is more stable and more difficult to extract from zinc and iron.
