Valorisation of acid mine drainage waste for synthesis of …
The primary aim of this work was to produce ferric ammonium sulfate (FAS) from acid mine drainage (AMD). AMD with a Fe content of approximately 240 mg/L was used as a matrix to model FAS formation under different solution concentrations of Fe and S (as ferric sulfate and sulfuric acid). This approach offered the benefit of identifying boundary ...
