  • Mine Water Treatment Solutions for Discharge and Re-Use

    While the major wastes generated by mines are waste rock, tailings and overburden, the majority of emissions can be found in discharged mine water. As mine water accumulates when the water level overflows the depth of an open pit surface mine or an underground mine, the water must be pumped or drained out of the mine to ensure safety and stability.

  • Pit lakes are a global legacy of mining: an integrated ...

    Pit lakes form when open-cut mining operations cease and the remaining pit fills with ground, surface and rain water. Mine pits, and therefore pit lakes, tend to have high depth-to-surface-area ratios with relatively flat bottoms and steep sides in order to minimise resource extraction costs (n.b., for the purposes of this review we are focussing on large mineral/coal mining pits as in Figure ...
