METHOD OF IRON ORE PROCESSING Russian patent published in 2016 - IPC C22B1/24 

FIELD: metallurgy.

SUBSTANCE: ore is screened to coarse, medium and fine classes. Coarse grain ore is subjected to sensory separation with the extraction of rough concentrate and final tailings while the rough concentrate is additionally screened to medium grain size and subjected to magnetic separation to get the final tailings and concentrate. Medium class ore is subjected to sensory separation to get the final tailings and rough concentrate while the latter is subjected to magnetic separation to produce final tailings and concentrate. Concentrates produced from the coarse and medium class ore are subjected to undersize of grain size equal to that of fine class and oversize used as the metallurgical stock. Note here that the fine class ore is subjected to magnetic separation to get the final tailings and concentrate. The concentrate is combined with undersize produced from coarse and medium classes and pelletised.

EFFECT: produced agglomerate with high content of iron making the high-quality metallurgical stock, simplified process.
