Belt Magnet on Screen Discharge (2 replies)

We have a problem with scat steel buildup in our gold gravity circuit and are looking at solutions to remove it for a steel buyback program. One of the ideas discussed was getting a new screen installed for our cyclone underflow and installing a belt magnet on the discharge end of the screen to remove the scat and funnel it into a scat reject chute. I was wondering if anyone has ever tried putting a belt magnet on the end of a screen before as we haven't seen any examples of it done before. Thanks

It depends on how you do it. Remember that most vibrating screens are made of steel, which the magnet will attract, effecting the action. Having screen discharge on to a conveyor belt, with magnet on that would work.

From a metal recovery perspective a good idea as metal is well presented to the magnet. Issue is any steel will become magnetic. Have done this before with stainless on the discharge of the screen.
