Thanks for that - Ore sorters also in use at VTX gold mine (take a look, they work well) and proposed for AW1's storm copper project.
But obviously they wont work in, for example, an ore where the gold is fine and widely spread over the whole ore body (that was the type of ore at Mt Morgan, I recall from memory)
Thanks again for history, always good to know. I'm here for the price appreciation of tungsten, into USA by current off-take agreements.
Cheers.
