Tailing/Retention Ponds

Tailings ponds, also called mine dumps, oil sands, tails, and retention ponds are the materials left over after the process of separating the valuable minerals from hard rocks. Tailing ponds typically represent an additional cost that mining companies need to factor in before starting their operation. When responsible mining companies operate tailing ponds, they often incorporate the cost of rehabilitation and proper closure of tailings areas in the mining costs and activities.
