IRON PRODUCTION FROM WATER SUSPENSION OF PARTICLES OF IRON COMPOUNDS ORE AND DEVICE TO THIS END Russian patent published in 2014 - IPC C21B13/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to nonferrous metallurgy, particularly to production of metallic iron. This method comprises formation of initial stock composed of water suspension containing iron compounds produced by introduction of iron ore particles into preset water volume. Said initial stock is displaced through serial processing zones. Here, metal is reduced with the help of carbon contained in gases fed to said zones. Variable rotary magnetic fields generated in said zones allow deposition of metal particles, their accumulation and discharge of finished metal. Note here that this process is conducted at continuous processing of said stock. Used water suspension features dispersity of iron ore particles of 0.001-1.0 mm and their content of 40-70%. Said variable rotary magnetic fields feature intensity in processing zones of 1*10⁶-1*10⁷ A/m and frequency of 40-70 Hz, in amount of 2 to 6, finished iron yielding as iron granules sized to 4-10 mm.

EFFECT: decreased electric power consumption, some 8-15 times, non-polluting process.
