The Application of Xanthate in Froth Flotation Process ...

2019-4-11  4. Xanthate Application in Galena Froth Flotation. The surface of galena is hydrophobic, so it’s easy for flotation. Xanthate is the common collector for the flotation of galena. When the pH is high, the galena is easily floated by the ethyl xanthate. The optimum pH for flotation is 7-8, which can usually be adjusted with sodium carbonate.

Floc flotation of galena and sphalerite fines - ScienceDirect

2001-1-1  At the given reagent and operating conditions, floc flotation increases the floatability of the galena and sphalerite fines over 30% ~ad 50% in the range of pH 5 to 8, respectively, in comparison to the corresponding conventional flotation. Clearly, floc flotation is an effective means of recovering galena and sphalerite fines.

Galena - Sphalerite Flotation Separation Method

2016-4-23  The problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue. The association of the minerals and gangue requires a 65 mesh ...

OPTIMISATION OF THE SELECTIVE FLOTATION OF

2014-12-10  flotation recoveries of galena and sphalerite are discussed in Chapter 5. The flotation results indicate that high dosages of xanthate collector of long chain length such as PNBX are detrimental to the flotation selectivity between galena and sphalerite. As expected, Cu(II) is a much stronger activator for sphalerite than Pb(II) ions. It is also

Flotation Froth - an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

1 Froth Flotation – Fundamental Principles

2009-8-27  1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and
