Waste rock is often deposited in piles or heaps close to the mine to minimize transports. As waste rock is exposed to air and water, a weathering process will proceed. Weathering of waste rock could contribute to the generation of an acid drainage (called acid rock drainage (ARD) or acid mine drainage (AMD) when in association with mines) with high contents of metals, especially if sulfide
