The article presents the results of laboratory studies on the extraction of iron from acidic waste solutions of the process of bacterial leaching of sulfide gold-bearing concentrates. The aim of this work is to extract iron from technogenic arsenic-containing acidic wastes, to increase the efficiency of using mineral raw materials with obtaining additional products. The studies were carried out on a solution taken from the biooxidation unit of the NMMC. The main task of this work was to determine the optimal parameters for the processing of acid waste solutions and the separation of iron from the solution without arsenic impurities. Based on the results of laboratory studies, a technological scheme was proposed that includes the precipitation of iron and arsenic from acidic effluents with ammonia water and the removal of arsenic from the precipitate by dissolving with caustic soda.
