Descriptions are given of selective flotations of titanium and zirconium ores by separation of zirconium into froth product with titanlum remaining in the unfrothed state. Flotation is based on a mineral reaction to reagents in presence of nitrogen. Replacement of oxygen by nitrogen followed by flotation in nitrogen flux resulted in high zirconium concentrate 56.68 to 65.84% ZrO/sub 2/ and 77 to 79.5% extraction and, 89.64 to 90.47% TiO/sub 2/ in the unfrothed state, with 84% extraction. The zirconium concentrate retained only 3 to 5% TiO/ sub 2/, while rutile contained 6 to 7.5% ZrO/sub 2/. The selective flotation of ilmenite-zirconium with small volume of oxygen in the puip resulted in 60 to 65% zirconium concentrate with 1.75 to 5.5% TiO/sub 2/ and 50 to 58% ilmenite with 6 to 19% ZrO/sub 2/. It is shown that nitrogen saturation of aqueous media produces effective separation of titanium and zirconium with minimum amount of saturation. (R.V.J.)
