The paper discusses a flowchart of flotoclassification (size classification while floating) within a closed circuit of grinding, with froth treatment in converging chutes during processing of cupper sulfide ore. The closed circuit of grinding with flotoclassification is analyzed theoretically. A comprehensive description of simulated closed grinding circuit with and without flotoclassification is given. The copper size grading data after wet screening and in flotoclassification are compared. The experimental testing of flotoclassification with froth treatment in converging chutes is presented as a case-study of Elenovskoe copper ore. It is shown that flotoclassification included in the closed grinding circuit produces standard quality copper concentrate, tailings and middlings sent to the next flotation stage, in amount of 60% of initial feedstock, which reduces machine hours, energy usage and capital input in flotation. An innovative flotoclassifier is designed, with jet and electrochemical aerators arranged in a converging chute. The relevance of the flotoclassification within the closed grinding circuit with froth treatment in converging chutes consists in improved performance of the technology thanks to reduced over-grinding of minerals.
