抄録

One of the chief problems in the new UCHINOTAI project in KOSAKA division, DOWA Mining Company, is the determination of the milling tlowsheet treating “KUROMONO” (Black ore).<BR>“KUROMONO” is a complex sulphides ore, extremely finely disseminated chalcopyrite, chalcocite, covellite, tetrahedrite, tennantite, galena, sphalerite, pyrite, gold and silver, barite and minor amount af gangue minerals.<BR>Due to the difficulty of liberation and similar floatabilities of component minerals, this are has been known very hard to be separated by the usual flotation procedures using cyanide and/or zinc sulphate.<BR>This article deals with the characteristics of liberation of component minerals obtained by microscopy and some flotation tests using sulphur dioxide which have given fairly better results than cyanide procedures.
