In the present paper dealing with the copper ion activation for pyrite, extents of effects of activation and floatabililty were comparatively studied for six kinds of pyrite gotten from different five mines in Japan namely Hanaoka, Yanahara, Toyoha, Matsuo and Osarizawa. Also the mineralogical properties of these pyrites such as chemical, physical and crystallographic were investigated.
From the above experiments, it was shown that copper ion activated every pyrite tested as well as that of Yanahara mine. The extent of effect of activation, however, was somewhat different in the pyrites gotten from different localities. Relatively large degree of activation was found in the pyrites from Yanahara, Hanaoka and Toyoha.
It was also shown that there are some differences in floatability of the pyrites tested. The floatability of the pyrites from Toyoha and Osarizawa was lower than the other.
The results of these differences in activating property and floatability of the pyrites tested was considered in relation to the mineralogical properties, which seem to depend on the geological formation, but it was difficult to ascertain the relation between them.
