Abstract: The article presents a rational technology for processing old tailings and slime (cyclone overflows) of the -25+0 microns class at tailing dump No. 1 of the Norilsk Processing Plant. One of the current and urgent problems is the lack of an efficient technology to process the slime part of old tailings with fine particles of useful metals, which is not processed and is transferred to temporary tailing dump. Current development state of the flotation equipment and technologies allows to consider the problem of coarse-size particle flotability generally solved. The results of pilot testing of the Allflot pneumatic flotation cell that operates at the 5% content of solids in the slime at Nordinves LLC are presented. Comparative materials are provided on the Allflot re-treatment slurry flotation cell (500 l) and a laboratory mechanical machine (1.5 l). The results of qualitative and quantitative calculations of the flotation process as applied to the slime fraction of old tailings are given. Conclusions about the economic feasibility of using the Allflot Pneumatic Flotation Machine for slime beneficiation are made.
