Abstract Basic experiments were conducted to establish the feasibility of foam fractionation in the treatment of acid coal mine drainage for the removal of the metal ions iron, calcium, manganese and magnesium. The independent variables controlling foam separation of metal ions were determined to be the concentration ratio of surfactant to iron, the air volume throughput, the foam drainage time, the total dissolved salt content and the type of surfactant used. The major part of iron, calcium, manganese and magnesium can be foam separated from acid solution by proper control of the independent variables. Reduction of residual surfactant concentration in the treated water and reduction of water entrained with the foam are two areas in need of further investigation. Foam separation was tested on acid drainage, partially lime neutralized drainage and complete limestone neutralized drainage. Tests on model solutions indicate that treatment of raw acid drainage is most feasible at present. Operating and capital costs are estimated for 0.1 and 1.0 MGD batch treatment plants. (Author)
