Project Description

The ultimate source of most of the nitrogen cycling at a mine site is the ammonium nitrate-based explosives used in the excavation of the mine. Waste rock, a by-product from the excavation of non-metalliferous rock in mining activities, often contains adsorbed nitrogen compounds (ammonium and nitrate) that are residues from the detonation of the explosives. Once the waste rock is deposited on the ground surface, the percolation of rain and snowmelt through the deposit will leach the nitrogen compounds, potentially impacting local recipients.
