    How Bulk Ore Sorting Can Reduce Water and Energy Consumption

    Grinding and crushing of ore is energy intensive and accounts for approximately 3-5 % of the world’s power usage. Every ton of waste that is not processed reduces comminution costs and the associated wear and maintenance costs of the equipment. Early waste rejection can reduce the processing plant and tailings dam footprint and capital.
