This work studied the treatment of and metal recovery from a synthetic acid mine drainage (AMD) containing 500 mg L⁻¹ copper (Cu²⁺) and iron (Fe⁺³), and 50 mg L⁻¹ nickel (Ni²⁺) and tin (Sn²⁺) by using a bioelectrochemical system (BES). The presence of electroactive bacteria improved the performance of such reactor configuration, by contrast with systems with abiotic anodes.
