The tailings dumps of the ironore mining-reprocessing enterprises exert extremely negative influence on the environment, but at the same time, under the conditions of the impoverishment of iron ores they are potential raw source. In connection with this, a question of involvement in processing of the tails containing iron is extremely urgent. In the article the technology on processing of the waste of the beneficiation of iron ores is suggest. In this case the clotting of the obtained concentrates can be carry out by briquetting. In the work are also given the results of researches of the iron-containing tails concentrating and briquettability of the concentrates obtained of them.
