Ore Sorting Strategies In Mineral Processing

For successful mineral processing design it’s critical to evaluate the possibility of preconcentration or waste diversion before grinding. Mess up this step and you could be hit with avoidable downstream CAPEX and OPEX costs. At its core, preconcentration means exploiting particle differences as early as possible so that waste material isn’t unnecessarily fed to the mill and then deposited ...
