Treatment and recovery of iron from acid mine drainage: a ...

The acid mine drainage (AMD) formed during copper mining and smelting has a low pH, high sulfate concentration, and large amounts of valuable metals such as Fe, Cu, and Mn. In order to achieve step-by-step recovery of these resources, it is necessary to first remove high concentrations of iron from the wastewater.
