METHOD FOR CONCENTRATION OF MIXED IRON ORES Russian patent published in 2007 - IPC B03C1/00 

Abstract RU 2290998 C2

FIELD: process for concentration of iron ores, may be used in mining and metallurgical industry.

SUBSTANCE: method involves grinding basic ore; classifying ground material into sands and discharge fractions; providing additional grinding of sands and returning additionally ground sands for classifying of additionally ground material; providing primary desliming of discharge fraction; performing main magnetic separation for producing of rough concentrate and tailings; separating concentrate and tailings at final magnetic separation stage; filtering concentrate; subjecting discharge fraction resulted from classification of ground material to control classification; directing control classification sands for main magnetic separation; directing rough concentrate for rough concentrate classification and providing additional grinding of sands at second additional grinding stage; returning additionally ground sands for classification of rough concentrate of main magnetic separation; directing discharge of rough concentrate classification of main magnetic separation for primary stage of discharge desliming process; directing condensed primary desliming stage product for further magnetic separation in order to produce concentrate adapted to be directed for classification and additional grinding of classification sands at third additional grinding stage; directing control classification discharge and rough concentrate classification discharge of further magnetic separation for further desliming stage; directing condensed product of further desliming process for final magnetic separation; discharging magnetic separation tailings into final tailings.

EFFECT: increased efficiency in concentration of mixed iron ores.
