Furthermore, the powders of artificial hematite are investigated in connection with the aerophilic charactor previously reported.
They are fairly floatable in a flotation test without collector, however their recovery increases as the addition of xanthate is increased. Xanthate is taken up evidently upon the surfaces. After the immersion in water for a long time, the response of them to xanthate is considerably reduced. They are restored to the former slate by the drying process following the above treatment. The floatability of degassed powders at 150°C in vacua is decreased to some extent.
Then, it is considered that the adsorbed gas phase gives an effect on the floatability of artificial oxide coupled with the surface structure by itself, especially in the presence of the xanthate-type collector.
