Sewage treatment of Olimpiadinsky gold concentration plant is investigated. Comparison of two schemes of clearing is resulted: the standard physical and chemical scheme and LLC "Bacor-filter-ceramics" scheme. The technology with application of filtering apparatus of LLC "Bacor-filter-ceramics" has shown good results. Efficiency of sewage treatment on the given method is 100 %. The offered technology can be used for sewage treatment both for the organization of water-circulation of factory water supply, and as prior operation for the purpose of the further advanced clearing for needs of a national economy. The quantity of operations is reduced at primary treatment. Economic benefit is confirmed by additional extraction of a valuable component (~250 Au kg/year) and reduction of expenses on reagents.
