    The Kalahari process beneficiates fine and ultrafine iron ore material to produce a 62-66% Fe content. In areas where water is scarce, the process can be coupled with a water reticulation system which produce a dry product, dry tailings and clear water for reuse. The dry tails can therefore be co-disposed, eliminating the need for slimes dams

    Feb 14, 2018 If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you're missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these additional stages enter the equipment line
