What does acid industrial wastewater contain
Mining & Hydrometallurgy - DuPont
Mining & Hydrometallurgy - DuPont

Wastewater produced through mining can come from many sources, including natural precipitation, hydrometallurgical processes, or acid mine drainage (AMD). AMD is created when sulfide minerals are exposed to air and water, producing sulfuric acid. All of these wastewaters typically contain heavy metals.

The concentration is usually 0.01-0.05 % cyanide, or 100-500ppm. It should also be noted that the alkalinity of this solution must be high enough such that hydrogen cyanide is not produced, which is a very toxic gas. This is more important when sulfide minerals are in the ore, because they will oxidize, consuming oxygen and generating ,acid,.

In the case of ,hydrometallurgy,, the ore is dissolved into a pregnant liquor which contains cationic metal ions or anionic metal complexes. These ions can be recovered via IER and membrane filtration. Although metal recovery is often the main objective, there are other cases where the recovery of metals as by-products can be valuable both financially and environmentally.
