As Hitachi Mine Mill is depending its supply of water on reclaimed water, a study was made to find- out its effect in flotation. The study showed that the remaining copper cyanide complex ion was the principal factor in bringing about an effective result in copper pyrite differential flotation.
A study was also made to find out the effects of other constituents in copper pyrite differential flotation.As regards the depressing action of copper cyanide complex ion, it was found out on an experimental scale that the desorption of xanthate adhering to pyrite minerals would be caused by this ion, while at the same time, a theoretical study was made on this matter.
Furthermore, a study was made to find out the relation-ship between the nature of water used- and the result of flotation in actual operation. By these means, a standard was established in the nature of water for use in actual operation.
