Heavy Metal Pollution from Gold Mines: Environmental ...

2016-10-26  Environmental pollution from gold mines is associated mainly with the release of harmful elements from the tailings and other mine wastes. The infiltration of water through sulphide- containing tailings piles and ponds, surface and underground workings, waste and development rock leads to leaching of large volumes of metals like Zn 2+ , Ni 2 ...
