Predicting mine waste environmental impacts before it’s too late. Mining for precious, base and ferrous metals can result in millions of tonnes of tailings and waste rock, which if left unmanaged can have dire environmental consequences. Poorly designed storage facilities can potentially leak pollution for centuries or even millennia.

The mined rock is transported to the processing site and stockpiled. The material then is crushed. Depending on the degree of cementation, several stages of crushing may be required to achieve the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing.
