ABSTRACT
The article presents the results of a study on the elevation of gold-bearing sulphide flotation efficiency by using oxidants. The study is due to the need for a clearer understanding of the processes occurring when the oxidizer acts on the surface of the minerals and the various inclusions within, and what range of factors play a key role in this process. Evaluation of process efficiency was conducted by analysis of eH-potential and air-flow rate influence on the sulphide minerals recovery in the concentrate.
