After lead flotation at optimum pH 8, the flotation of zinc at a different pH (5–11.5), with two collector types, was performed to study the recovery and grade of zinc in the zinc concentrate.
Flotation is widely used to concentrate low-grade zinc ores (using anionic, cationic, or mixture of anionic/cationic routes). The choice of route depends on the main zinc-bearing mineral in the deposit and its associated gangue mineral.
The direct flotation of zinc oxide ore using anionic collectors or mixed anionic/cationic collectors shows poor separation between zinc oxide minerals (such as smithsonite) and other carbonate minerals (such as calcite). Therefore, the development of a new or effective collector for the flotation of smithsonite from calcite is needed.

The most common flotation collectors used commercially for the treatment of zinc oxide minerals are cationic collectors and sulfhydryl collectors, such as amine and xanthate . As is well known, slime causes significant negative effects on the flotation with amine, and xanthate exhibited a relatively poor collecting capacity for the zinc oxide ...

Flotation of zinc oxide ore using cationic and cationic-anionic mixed collectors 155 Conclusion From two amine collectors used in this study, Armac T acts a little more selectively than Armac C and results in smithsonite concentrate with higher Zn grade while Ar- mac C is effective in enhancing the recovery of Zn. The KAX–Armac C mixed collec ...

The mixed cationic and anionic collectors were found to be as effective as the HF reagent system in obtaining high grade feldspar concentrates. Iron-bearing raw marine sand consisting of quartz (88%) and feldspar (10%) was treated by Mathieu and Sirois (1984) using the same combination of anionic-cationic promotors.

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
The result of two-stage cleaner flotation showed that zinc grade could be increased up to 16.2% with zinc recovery of 61.39%. A representative sample of zinc oxide from Dashteh Sefid mine was obtained and then mineral characterization studies were done. The results of mineralogical analysis showed that the main zinc-bearing minerals …

method for the recovery of oxidized lead and zinc minerals from ores at present is flota-tion (Onal G. et al., 2005). The flotation of oxidized lead and zinc minerals, particularly zinc minerals, is much more difficult than the flotation of corresponding sulfide miner-als. Hexyl and amyl xanthates are capable of collecting smithsonite.
