METHOD OF FLOTATION OF BARITE CONTAINING ORES Russian patent published in 2009 - IPC B03D1/00 

FIELD: mining.

SUBSTANCE: invention refers to flotation concentration of minerals and can be used at processing of barite containing ores. The method includes preliminary treatment of pulp with regulator of pH-medium, with depressor, with a fat acid collector in form of the mixture of modified soap stock, fat tall acids and Asparal F, and flotation with above said collector. Preliminary water preparation is performed before flotation, it consists in softening re-circulated water with lime and soda, in sedimentation by method of decantation and in separating water from the produced sediment, and in introducing H₂SO₄ into softened water. The mixture of modified soap stock, fat tall acids and Asparal F is introduced in form of uniform solution at the ratio of 1:1:0.2.

EFFECT: increased efficiency of flotation.
