ABSTRACT
As the result of theoretical and experimental investigations in laboratory and industrial scale physico-chemical models for optimal conditions of copper and iron sulphides activation flotation and depression have been derived, varied, and proven. Physico-chemical models derived are based on the mechanism of reagent action and themselves represent determined quantitative relationships between the concentrations of reagents ions in pulp. They can be used in plants as the criteria for functional units of automation systems in optimisation of technological processes of activation and flotation of copper and iron sulphides or depression of iron sulphides flotation.
