What sort of volumes of process water are we talking about and solids content and SG etc.
Start possibly with Deep cone thickeners, that will return the vast majority of your process water back into the process ware its needed specifically if your mining in arid areas.
The paste can then be dewatered further, please steer away from tailings dams! These are a life time manageable environmental disaster, a legacy of the mines and corporate greed our children will need to clean up.
Personally again depending on volumes I would NOT use a centrifuge due to the High power High Polymer/chemical demand, plus the paste/sludge is usually very abrasive warranting expensive tiling.
If your carbon footprint conscious then try a Belt Press.
