DEVICE FOR REGULATING FLOTATION AND FLOTATION CLASSIFICATION PROCESS Russian patent published in 2017 - IPC B03B13/00 B03D1/14 

FIELD: mining.

SUBSTANCE: device for controlling the flotation and flotation classification process, including the lighting device, the video analyzer, the laser foam level sensor and the controller, installed over the foam threshold of the flotation machine. The device is provided with a flow generator made in the form of a tray with a flat bottom and a tapered section, inclined in the foam discharge direction, installed behind the foam threshold in the foam discharge direction. The video analyzer and the laser foam level sensor are installed at right angle to the inclined tray bottom. The device is equipped with a device for measuring the foam product parameters during the flotation process, containing the foam product colour template with one or more colour elements corresponding by the colour characteristics to the foam product at a different weight fraction of a valuable component, and a spray-type device for cleaning the foam colour template.

EFFECT: increasing the accuracy of the foam product output analysis and the mass fraction of iron, reducing iron losses during enrichment.
