Tailingsfo La Coipa, Atacama Region, Chile

Dry stacking of tailings at La Coipa has been possible due to advancements in large capacity horizontal belt vacuum filters. The tailings (18,000t/d) are dewatered to contain 20% water content (depending on the specific gravity) allowing them to be either trucked or transported by conveyor to the disposal site. The conveyor system is mobile
