摘要：

In the grinding process of steel products, considerable amounts of grinding dust are generated, polluted with coolant (oil, oil emulsions), and non-metallic material from abrasive (silicon carbide, aluminum oxide and others). Grinding sludge generated as a result of this mechanism is a valuable source of post-industrial waste containing, apart from iron, such alloying elements as: cobalt, nickel, copper, tungsten, molybdenum, and vanadium. Considering the metallurgical value of grinding sludge, a method for recovering these elements from the sludge has been developed. The article presents a recycling method in a three-stage technological process consisting of sludge de-oiling, sintering, and re-melting in an electrical furnace.
