The effect of the oxygen potential on cohesion was examined by using the pulvenzed ore of iron sand, hematite ore, and magnetite ore The sample was kept under atmosphere by which the oxygen potential and the temperature were kept constant during the fixed time, and the state of cohesion was examined The temperature was an interval of 50℃ of 1173〜1423K, and the holding time was done in 15 min until 60 mm It has been understood to cohere easily in the oxygen potential in the stability area of the wustite in each pulverized ore Order of the tendency of cohesion was as follows, iron sand > hematite ore > magnetite ore SiO_2 and Ti0_2 of the mineral composition in iron sand are greatly related to cohesion. The surface of the ore particle melted, and the fusion of the ore particle each other was confirmed
