Joint aqueous leaching of read slime and greasy scale

A new approach to the development of utilizing two types of anthropogenic waste, namely, red slimes from processing bauxites (including Ural plants) and grease scale of the rolling production, which involves their joint processing with the acquisition of a product suitable for the recovery of the main components using blast furnace smelting for cast iron and alumina slag, is developed. To complete the investigations, a technological simulation of the processes of leaching, filtration, and drying is used. Optimal leaching parameters that provide a high filtration rate of the pulp suitable for the purification of industrial and sanitary waters and the acquisition of 52–56% iron in the cinder are established.
