How Bulk Ore Sorting Can Reduce Water

May 26, 2021Processing less waste and low-grade materials results in a reduction in the use of water, which can reduce water supply costs or operating costs of a desalination plant and the filtering of water at the end of the process. It also reduces the amount of water that ends up in a tailings dam. Grinding and crushing of ore is energy intensive and

If the metal price increases, it may seem intuitive to lower the cut-off grade since the low grade material can be mined at a profit. However, the better decision is often to increase the cut-off grade instead. Processing the higher grade material will yield an increase in the amount of valuable mineral produced.
