Effect of Ca2+ and Mg2+ on Floatability of Smithsonite

The flotation tests were performed using purified samples from Lanping mine of China by the microflotation technique. The Ca2+ flotation results showed that the recovery of smithsonite decreased from 89.81% to 83.92% and the recovery of hemimorphite decreased from 84.83% to 76.03% when increasing Ca2+ concentration from 200mg/L to 1000mg/L.

The role of S(II) and Pb(II) in xanthate flotation of smithsonite:

For S(II)-conditioned smithsonite, a layer of ZnS formed on the smithsonite (ZnCO3) substrates; this newly formed ZnS coating was amorphous or poorly crystallized. For smithsonite samples conditioned with S(II) and Pb(II), the microstructures and the phase constituents, obtained by AFM and XRD analyses, confirmed the formation of the PbS species with a cubic

Carrier flotation is a common technique used to improve flotation recovery of ultrafine ores. In this study, we used coarse polystyrene as the carrier material to enhance flotation recovery of fine smithsonite (ZnCO3) particles. Sodium oleate was used as the collector and played a role in the adhesion of fine smithsonite to polystyrene due to its amphipathic properties. The carrier

Effect of Ethylenediamine on Smithsonite Flotation

In this paper, ethylenediamine (NH 2 CH 2 CH 2 NH 2) was selected to active flotation of smithsonite using dodecylamine as collector. The effect of ethylenediamine on flotation efficiency was conducted; the results showed that without addition of ethylenediamine, the recovery of smithsonite was only 32.85% when the usage of dodecylamine-hydrochloride as

The effect of reagents on selective flotation of

1/8/2009Flotation is the commonly used method for beneficiation of smithsonite and other oxidized lead and zinc minerals (Ciccu et al., 1979, Pereira and Peres, 2005). Separation of oxidized lead and zinc minerals from their gangues by flotation is extremely complex due to the similarities in physico-chemical and surface chemistry of the constituent minerals.

What Is Beneficiation In Mineral Processing?

Beneficiation means converting the mined material into a valuable product. It is the only way to exploit large deposits, even low-grade and/or complex mineralogy. It allows the mining of ores not only metal resources but all useful substances such as sands, limestone, granites, barite, fluorine, etc The species enriched constitute the concentrate, which will, in turn, be the raw material
