Heavy Metals and Arsenic Treatment in Mining Wastewater | P2W

The regulation around the world for ,heavy metals, has become more rigorous in recent years and today the removal process is a required feature in all mining sectors. ,Metals, in the ,wastewater, are usually found in their salt forms which lead to the fact that most of the ,metals, are totally soluble in the liquid phase and are difficult to remove by simple filtration or other simple physical processes.

Heavy Metals Removal | AQUAMAG
Heavy Metals Removal | AQUAMAG

Metals, Removal: AQUAMAG ® can effectively remove most ,heavy metals, from solution with only nickel and cadmium proving to be problematic to precipitate. If removal of these two ,metals, is necessary, AQUAMAG ® can nevertheless be added initially to raise the pH of the ,wastewater, to 8.5, followed by the addition of caustic soda to raise pH to the level necessary to remove nickel and cadmium.
