ABSTRACT:
The present invention relates to ore lumping processes in ferrous metallurgy and can be most efficiently utilized in non-roasting methods of producing pellets from iron ore concentrates with moisture content of 7 to 15%.
The given method of producing pellets provides for preliminary preparation of a mixture from ore concentrate with particle size less than 0.83 mm and binding material in the form of calcium oxide and magnesium oxide followed by hydration of this mixture to produce a hydrated mixture, thereafter this hydrated mixture is introduced into ore concentrate to produce a homogeneous mixture containing 4 to 15 weight percent of binding material with the following pelletizing of the homogeneous mixture to produce pellets by curing them in the medium of saturated steam at a temperature of 120-225.degree. C during a time period of 1 to 12 hours.
