By the use of a small sintering pan and drum pelletizers, relations between the following two pretreatments of sintering raw materials, sintering conditions and the strength of the sinter were studied. In one pretreatment method which is commonly called semipellet treatment, small pellets were prepared separately and mixed in fine raw materials, and in the other method commonly called fore-pellet treatment, all raw materials were charged in a drum pelletizer. The results of this experiment are as follows : 1) Pretreatment were very effective in the sintering of fine iron ores. 2) The fore-pellet treatment was more effective in the sintering of fine iron ores than the semi-pellet treatment. 3) The strength of sinter was a little improved by the two pretreatments above mentioned.
