1. Barite-fluorite Ore Flotation Process
Professor Li Mingfeng treated a barite-type fluorite ore containing 37.79% CaF₂ and 49.80% barite. After bulk flotation, a mixed fluorite-barite concentrate was obtained. Barite was then floated through a process of "1 rougher and 4 cleaners," and fluorite was recovered from the tailings through a process of "1 rougher and 3 cleaners."
