Removal of Sulfate and Metals from Wastewater of a Mining Enterprise by a Dual Sorbent System: A Case Study

Abstract This paper presents the results of wastewater treatment at a mining enterprise developing complex ore deposit in Murmansk region, Russia. The main pollutants are sulfate, manganese, and strontium. For this treatment, two-stage scheme was proposed tested using two sorbents (at pH 6): an aminated peat biosorbent to remove sulfate commercial sorbent based on mineral brucite metals. Optimal conditions were established for purifying manganese strontium ions level maximum available concentrations water bodies fishery purposes.
