Bulk ore sorting improves profitability and sustainability
A perfect complement to in-pit crushing and conveying. Because the natural heterogeneity of the ore makes sorting more effective, a bulk ore sorter should be placed as early as possible in the process. This also avoids extra costs and the lost capacity associated with treating non-economic material.
