– Ammonia Nitrogen Removal from Mine Water at a Northern Quebec Gold Mine


A gold mine in northern Quebec was experiencing high levels of ammonia nitrogen in their water discharge from blasting operations. Authorities mandated the mine to reduce ammonia levels in the mine water discharge to under 10 mg/L to protect wildlife from ammonia toxicity. Traditional biological methods to ammonia abatement present certain challenges, given the northern climate and the unsteady flow of water from the mine. E2Metrix was approached to investigate whether its patented ECOTHORTM electrolysis technology platform could be used to address these challenges. Through in-house and onsite testing over the second half of 2017, ECOTHORTM demonstrated its capacity to control ammonia nitrogen to under 10 mg/L. This presentation will outline the results from this project as a show case for this industry.
