The processes of production of pig iron, steel and cast irons are accompanied by the formation of a significant amount of slag. This waste can be sent to re-smelting, however, if it contains a high content of impurity components, it is sent to the dump as waste. This waste contains 40 – 50 % of iron compounds, with a developed surface. In the framework of the work, it is proposed to use slag as a feedstock to obtain complex coagulants. Complex coagulants are highly effective reagents used in wastewater treatment processes for hydrotreating parts, gas purification, and also galvanic wastewater. As part of the studies, the high efficiency of complex coagulants in the processes of wastewater treatment of galvanic production from chromium (VI) ions was confirmed.Keywords: Recycle, slag, water treatment, complex coagulant, wastewater
