METHOD OF FLOTATION OF ORE AND FLOW LINE FOR IMPLEMENTATION OF THIS METHOD Russian patent published in 2009 - IPC B03D1/02 B03D1/04 B03B7/00 

FIELD: mining.

SUBSTANCE: method consists in ore crushing, in stabilisation of energy state of flotation disperse system, and in flotation with flotation reagents-collectors. During flotation into composition of flotation reagents-collectors there are additionally introduced N-acyl-sarcosine (oleil-sarcosine) at ratio of from 1:0.5 to 1:1. The method is realised on a flow line for ore flotation, including successively connected facilities for crumbling, classification, and stabilization of energy state, also a facility for supply of flotation reagents-collectors, and a flotation machine. The flow line is additionally equipped with a mixer-measuring device assembled before flotation machines and devices for supply of N-acyl-sarcosin arranged before the mixer-measuring device.

EFFECT: increased efficiency of ore concentration.
