Ion flotation of twenty kinds of metal ion in hydrochloric acid in the range of 0.1 to 6 N was investigated in the presence of a cationic surfactant, cetylpyridinium chloride (GPC). Ten ml of the metal standard solution and a certain volume of CPC standard solution were transfered into a glass-filter cell (i. d. 2.7 cm, height 20 cm) and then the mixture was diluted to 12.0ml with water. Nitrogen gas saturated with water was bubbled through the solution containing metal ion or (4〜5)×10^<-4> mol/l and CPC of (2〜4)×10^<-3> mol/l for 20 to 30 minutes. Zinc(II), antimony(III) and bismuth(III) were removed completely at the hydrochloric acid concentration of 1.2, 0.75 and 0.4 N. At the hydrochloric acid concentration of 0.01, 0.10, 0.42, 0.43, 5.0 and 5.8 N, 97, 95, 93, 87, 97 and 97 per cent of thallium(III), mercury(II), tin(IV), cadmium(II), iron(III) and garium(III) were removed. Nickel (II), cobalt(II), manganese(II), aluminum(III), indium(III), chromium(Ill), titanium(IV) and zirconium(IV) were not removed at all in this concentration range.
