Research of Laws Pyrite-Bearing Slag Flotation of Copper Melting in Water used Change Settings

The article presents the results of studies of the effect of conditioning method of circulating water in the flotation of refractory copper slag in Ural region. The mineralogical characteristics of slag are given, the slag feature, which de-termines the efficiency of the flotation to extract copper from the slag not in the alkaline environment, as it is usual-ly in enterprises, but in the slightly acidic and neutral pH range of the environment is disclosed. The influence of the method of water conditioning and of the concentration of metal ions in the prepared water on the performance of flotation is found.
