Mine Tailings
NAWE focuses on our mining clients' ultimate need to achieve and maintain environmental compliance with acceptable operating costs. Results from treatability tests have demonstrated that NAWE's aerated wetlands can effectively remove ammonia from mine tailings and can treat a high volume of wastewater from mining operations with a minimum of amount of operation and maintenance cost.

Rosebel Gold Mines (Suriname, South America)
Rosebel Gold Mines N.V. (RGM), a Cambior subsidiary, contracted NAWE and Jacques Whitford to design an engineered wetland (EW) system to treat water from RGM's tailings pond at its gold mine and mill facilities in Suriname, South America. The discharge from the engineered wetland will meet Cambior's high standards for pollution control, which means the discharge will have very low concentrations of ammonia.
