DetailsThis is often a large pond, where the tailings are stored together with process water. These ponds use engineered (earth) dams and sometimes the surrounding environment (such as valleys) to create a confined space. Therefore, the common terminology for a TSF is a 'tailings dam'. Why mine 'waste' from a tailings dam?
