Tailings - Mt Todd Gold Mine

Tailings are the product of processing ore to recover the contained metals. After extraction from the mine, the ore is crushed and subsequently ground to a particle size that allows for the liberation of the metals from the host rock. Most mineral deposits are composed of many different minerals, some of which contain metals.
