We recognize that, by not releasing water, we are creating an increasing storage challenge that is not acceptable to our stakeholders. As well, from a reclamation perspective, it is necessary to build a final landscape with a hydrology that connects seamlessly to the surrounding environment.
We have conducted research on tailings water treatment using coke, a byproduct of our process.The treatment is similar to using a home water filter. The coke, which is almost pure carbon, acts as a filter that captures contaminants and, most importantly, naphthenic acids. Bench-scale research shows the treated water is able to support aquatic life (see photo).
The technology has received patents in Canada and the United States.
