FLOTATION USING ACTIVATOR MADE UP OF METAL ORGANIC COMPLEX Russian patent published in 2011 - IPC B03D1/00 B03D1/18 

FIELD: process engineering.

SUBSTANCE: invention relates to foam flotation separation and activators used therefor. Flotation comprises using minerals dressing unit, producing flotation mix containing some amount of minerals to dress, and adding alkali-free activator thereto, alkali-free activator representing metal complex made up of coordinating metal ion and ligand wherein ligand-to-metal ion ratio varies from 2:1 to 1:2. In flotation, alkali-free activator is used consisting of coordinating metal ion and ligand that makes complex in water solution with preset pH varying from 2 to 12.

EFFECT: higher efficiency of flotation, reduced consumption of reagents.
