Development of methods and apparatuses for separation of minerals in magnetic fluids considerably increases efficiency of beneficiation of various ores. Production processes of ferrohydrostatic, magneto-adhesive and electrodynamic separation in large measure determine the prospects for further development of wet electromagnetic concentration. Industrial magnetic fluids are produced only from chemically pure raw materials, which is very expensive. Production of magnetic fluids from mining and processing wastes, firstly, decreases the cost, secondly, allows to utilize waste materials of hazard classes II and III, that at present are slowly accumulating at the sites of mining complexes and concentrating plants. Processing flow sheets were developed for production of magnetic fluids from iron-containing waste by means of the chemical condensation and electrochemical methods. The results of the studies show that magnetic fluids, produced by the proposed technologies, are distinguished by the properties that are similar to those of magnetic fluids, produced from reactive raw materials. With that, the cost of magnetic fluids, produced from mining and processing wastes, is just a fraction of the cost of magnetic fluids, produced from reactive raw materials.
