Ann: Efficiencies Identified For Expansion of Production, page-16

It could do. Graphite processing schematics suggest that there is a screening stage before and after grinding before entering the flotation stages.

I only remember the recommissioned plant having one "dry" vibrating screen. Due to the clay content of saprolite (which would be sticky) maybe this type of screener is a necessity if hydraulic mining is going to be implemented. Granted, Stevo!

Since Given is giving us the prompts like NL does with his graphite project, I think I may start looking into the potential cost savings of hydraulic mining aka NCZ. Zinc, after all, involves flotation processing.
