An end to tailings dams

A full scale implementation of this technology would allow mines to operate with a water make up ratio of 0.2 m3/tonne compared to traditional sand dams with a water ratio of 0.7 m3/tonne By enabling mines to reuse between 90 95 of their process water the filter solution would thus enable mining companies in Chile to reduce their fresh water intake by more than 70 .
