  • Hydro Float technology for coarse particle recovery

    The reasons for implementing coarse particle flotation in base metal and iron ore enrichment are twofold. First, by floating semi- liberated ore at significantly coarser sizes, such as 400-500 microns, the grinding capital and operating costs can be greatly reduced. Secondly, producing a coarser tailings product reduces the amount
