The causes leading to the technological equipment contamination of for rolling mills and consequently the environment are analyzed. The prospects of using the magnetic separators are substantiated. In order to reduce water consumption to a minimum by rolling production and to reduce the emissions of scale with oil products on its surface into a water body by ten times, high-quality treatment of reversed waterby permanent magnet separators with a fineness of 1–2 mkm is required. The mathematical modeling methods of the quality characteristics separation for monodisperse and polydisperse aqueous ferromagnetic suspensions are considered. It is shown that the required refinement can be achieved in multi-row magnetic separators.
