Strongly acidic wastewater (H 2 SO 4) with a high arsenic concentration is produced by many industries. The removal of arsenic by traditional sulfide (e.g., Na 2 S, FeS) from strongly acidic wastewater introduces cations (Na + and Fe 2+) to the solution, which may prevent the recycle of acid.

Acid mine drainage - Wikipedia
Acid mine drainage - Wikipedia

In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, and in such cases it is treated as acid rock drainage. This liquid often contains toxic metals, such as copper or iron.
