Tailings Fact Sheet

Tailings Fact Sheet

Tailings can be dewatered or modified in other ways prior to deposition. The current methods include: 1. Thickened tailings (which involves a process of dewatering to form a low solids content slurry); 2. Paste (which includes dewatering until the tailings do not segregate as they are deposited and have minimal excess water); 3.

Dry Processing

Dry Processing

The run of mine (ROM) processing can be done by two different methods – the wet and the dry processing. Wet Processing. After the wet processing, the muddy sludge produced at the mine is known as tailings. This waste is disposed of in dams. Dry Processing. This natural moisture processing without water does not generate tailings, so no dam is ...
