Tailings Ponds Up Close

Tailings are a mixture of water, clay, sand and residual bitumen that result from oilsands mining. They are stored in large ponds where the clay/water mixture is left to settle. Tailings ponds cover about 130 square kilometres of the oilsands region. Facilitated by CONRAD, Directive 74 has led to more collaboration within the industry, said Fair.
