To date, more than 110 mln. t of copper slags have been cumulated in the Urals. In recent yeras, the complex approach to the raw materials processing has been widely spread in the world. During the usage of this approach, the copper slags are considered as an additional source of copper. The copper slags processing technology is developed and implemented in Russia at the range of Ural concentration plants, included into the metallurgical complexes. One of directions of solving of old copper slags' filling problems is the processing of these slags on the nearest ore-dressing and processing enterprises, which have formed their own technology, equipment and water circulation for years. Detail research of copper slags of various metallurgical enterprises of Ural region made it possible to systematize and classify these slags. This research had its main tasks:
— definition of peculiarities of copper slags for the purpose of forecasting of possibility and grade of copper reextraction from these slags;
— definition of influence of pH and Eh parameters of the enterprise's water phase (where the slag flotation is planned) on its flotability.

Research of influence of conditioning of circulating water on the slag flotation made it possible to define the direction of development of copper reextraction technology from copper slags at the concentration plants, which process the copper and copper-zinc ores.
