Improved spray compositions for reverse froth flotation separation and their use are described, as well as methods of reverse froth flotation. The spray composition includes a sulfonated polymer modifier that can act as a dispersant and suppressor, and is suitable for reverse froth flotation of particulate material containing ultrafine particles. For example, the compositions and methods can be used to separate iron oxide concentrates from iron ores including silica, silicates, and the like. |
