Thus, investigated the reagent, which is a mixture of Trispropanilphosphine oxides, should be considered as an effective collector for flotation of sulfide copper-Nickel ore at the rate of 20 gso. The use of reagent SF-239 can be easily implemented in industrial practice and will allow you to avoid more expensive flotation - butyl Aeroflot.
Mar 26, 2021 Amine flotation process, also known as cationic collector flotation process, is a common flotation method of nonferrous metal oxide ore copper, lead, zinc. It uses the amines as collector for flotation, widely used in copper malachite, azurite and chloropyrite. The amine collector is selective to the copper oxide.

The ore deposit is located in the Lai Chan Province of Vietnam. This ore is heavily weathered ore, with more than 30 of the bastnaesite contained in the 7m fraction. The major host minerals present in this ore are barite and fluorite. Direct flotation of bastnaesite is not possible because of high barite and fluorite
Sep 24, 2019 Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic,which is suitable for lead-zinc ore.But the flotation of oxidized lead-zinc ore is a difficult one. In the treatment of lead-zinc oxide ore, it is complicated to choose flotation reagent and process flow.

Mar 25, 2015 Abstract. Different dispersants were added in the dispersion process to improve the efficiency of fluorite flotation. The types and dosage of dispersant on the improvement of fluorite flotation were investigated when the sodium polyacrylate SPA was used as the dispersant and its addition is 0.5, the concentrate grade of CaF 2 increased from 90 to 98 and the fluorite
For a zinc extraction plant in Tibet, there are much slime in the raw ore. According to the zinc ore characteristics, Xinhai adopted pre-desliming, zinc sulfide flotation and zinc oxide flotation process. Finally, the production indexes were stable and the recovery rate of zinc reached 69.56. .
