J. Paul Getty, the famous 20th-century American oil and gas tycoon, once noted: “If you owe the bank $100, that’s your problem. If you owe the bank $100 million, that’s the bank’s problem.” That’s the sort of conundrum facing Albertans right now when it comes to the massive tailings ponds created by the province’s oilsands companies. Those ponds contain approximately 1.4 trillion litres of water, the equivalent of more than 560,000 Olympic-sized swimming pools, and it’s about to come rushing down the Athabasca River — one way or another.
How liquid salt could be the answer to oilsands tailings ponds
Wastewater from oilsands mining operations have long been a challenge for Canada's energy industry, much of it ending up in industrial tailings ponds. But scientists and engineers at the University of Calgary are taking aim at eliminating watery tailings from the oilsands production process with the help of specialized liquid salt. Hot water is used in oilsands mining operations to extract the oily bitumen from the sand, with the resulting wastewater ending up in tailings ponds to settle and later be reused. Alberta has an estimated 1.3 trillion litres of fluid tailings sitting in tailings ponds.
