flotation of zinc and oxide

Influence of important factors on flotation of zinc

2011-10-1 · The most common flotation technique used commercially for the treatment of zinc oxide minerals is sulphidization with Na 2 S, followed by treatment with conventional cationic collectors, namely amine (Mckenna et al., 1949, Rey, 1954, Abramov, 1961, Önal et al., 2005, Pereira and Peres, 2005, Keqing et al., 2005, Hosseini and Forssberg, 2006a, Irannajad et al., 2009). The main flotation characteristics of cationic

Design and selection of flotation collectors for zinc

2021-1-1 · Froth flotation is the most popular method for the recovery of zinc oxide minerals. However, easy to slime, complex composition, high solubility, and reagent control difficulty (Chen and Tang, 2020, Ejtemaei et al., 2011) are severe obstacles on the recovery of zinc resource.

2016-9-29 · The studies on oxide zinc ore indicate a maximum bench scale flotation recovery of 84.5 % with zinc grade 24.5% in the presence of dodecylamine at pH 11.5. There are no significant variations in recovery of cationic and anionic and mixed collectors, however, amine and mixed collector flotation show to be more selective than anionic collectors.

Influence of important factors on flotation of zinc

Abstract In this study, the influences of important factors on smithsonite flotation are investigated. Dosages of sulphidizing agent and collector, desliming prior to flotation and the use of sodium hydroxide instead of sodium carbonate as the pH regulator are essential to the effective recovery of smithsonite in cationic flotation. The appropriate temperature for flotation was found to be 30
