FIELD: metallurgy.
SUBSTANCE: procedure consists in crumbling ore, in its mixing with carbon reducer and in mixture sintering. Also, before sintering ore is additionally mixed with carbonate slime; mixture is sintered in oxygen containing medium. Upon sintering arsenic and phosphorus are leached with solution of sodium hydroxide and simultaneously are subjected to wet magnetic concentration.
EFFECT: increased contents of iron at low contents of arsenic and phosphorus.
