Pioneering A New Approach To Mine Water Treatment

Recent regulations in Canada have refocused the mining industry’s attention on ammonia treatment in mining waters. When the “end-of-pipe” effluent limit for un-ionized ammonia was introduced last year, many mining companies began hunting for new, innovative approaches to achieve the revised target limit in their water treatment processes.

Alamos Gold was one such company. Faced with a myriad of technology options and alternatives, Alamos Gold engaged Golder to conduct a water treatment assessment for their Young-Davidson mine in northern Ontario to help them choose the best treatment approach for their needs. They sought an all-seasons solution that, once constructed, would require minimal operator attention. Alamos ventured outside the box when they considered and ultimately decided to employ the innovative Submerged Attached Growth Reactor (SAGR) technology, a new approach for treating and managing ammonia in cold water.

In the April 2019 edition of Canadian Mining Journal, Michael Bratty, Project Manager and a senior water treatment specialist with Golder, discusses the success of SAGR at the Young-Davidson mine and how this could be a game-changer for the mining industry.
