Capabilities of sonochemistry in flotation of ore minerals

Authors: Burov V. E.

A promising method of ultrasonic treatment is theoretically analyzed with regard to the improvement of solid mineral flotation efficiency. The theoretical framework of sonochemistry (acoustochemistry), and the effects induced in ultrasonic treatment of different media during mineral flotation are analyzed, including transient and steady-state cavitation, and the effect of acoustic emission force. The factors of the sonochemistry influence on flotation efficiency are explained, and these factors are primarily connected with ultrasonic cavitation and with acoustic emission force. The article identifies two main research areas addressed by the world scientific communities in the last two decades: ultrasound treatment of pulp or flotation agents before flotation, including the processes of emulsification or dispersion of the agents, removal of oxide films from particle surface, snf desliming in the supersonic field; ultrasound treatment during flotation, which exerts an influence on the size of air bubbles, separation of barren rock from high-value material, frothing, etc. Regarding application of ultrasound at flotation factories, the most promising approach is the ultrasound treatment of ore pulp, which promotes removal of clay–salt slimes and oxide films from the surface of mineral particles, and the preliminary sonochemical treatment of floatation agents, which changes many physicochemical characteristics of the agents and improves flotation efficiency thereby.

Keywords: flotation, ultrasound treatment, flotation agents, cavitation, flotation efficiency, acoustic emission, dispersion, desliming, pulp.
