Tailings Pond Volumes Increasing with Lower Grade Ores

Tailings Pond Volumes Increasing with Lower Grade Ores

January 5, 2023

The world’s 29,000-35,000 active, inactive and abandoned tailings storage facilities (“TSFs”) contain approximately 534 billion cubic meters (~14 trillion gallons) of wastewater.  With recent catastrophic failures, there is increasing regulatory scrutiny of TSF safety, but these efforts are challenged by ever-increasing amounts of TSF wastewater due to mining successively lower grades of ore (see article below) and also due to increased weather volatility.  Hence, the number of TSF failures is expected to continue to increase.   EcoVAP’s proven technology for evaporating this wastewater, thus reducing or practically eliminating the volume of wastewater at any TSF, can help reduce the operational cost and environmental risk of tailings wastewater disposal.
