Abstract: The article deals with finding the optimal floatation conditions for the final tailings of wet magnetic separation. To solve the problem, several laboratory tests were made using a floatation machine, which helped to determine the needed reagent composition, temperature and time of reverse cationic floatation. The home-produced FLON and foreign-made PA-14 reagents proved to be the most effective collectors for the final tailings of Mikhailovsky mining and processing plant. Hydrolyzed starch was found to be the most active depressor. The recommended concentrations of the collector and the depressor are 250 gram/ton and 500 gram/ton, correspondingly. The rebeneficiation of wet magnetic separation waste containing 32 % of iron and 60 % of silicon resulted in obtaining a concentrated product including 61 % of iron and 16 % of silicon expressed as oxide. The concentrate yield is 26 % of the initial load mass. The work also establishes the procedure for using the waste of iron ore beneficiation as a mineral filler for the composite binding materials.
