That is the theory with the gravity seperators and the secondary Heavy Media Separation in my post.

Nonetheless,it is not a straightforward concept but in theory can work in my opinion. The key is testing separation within a metalurgical context to test then models of infrastructure, so that again is something AVZ will need to. Also what happens in the lab generally doesn't translate to the field hence why looking at PLS for learnings as well to optimise the gravity sepaerators and secondary HMS processes. As I said don't want to be double handling.
