Flotation of zinc oxide ores by cationic and mixed

Oct 01, 2012Highlights In this study, for the first time, Armac T, as an amine collector, is used selectively for flotation of smithsonite. The mixed collector of Armac C and Armac T acts more effective than each of them alone. In the optimum conditions, the mixed collector consumption is significantly decreased. Using the mixed collector, there is no need to any depressant reagents. In the flotation

Jan 15, 2020Sulfoxy reagents, such as sulfite, metabisulfite, and bisulfate, are used extensively as depressants for sphalerite. The inorganic depressant zinc sulfate is used as a depressant in flotation processes because of its low cost (Boulton et al., 2001, Wang et al., 2019). Researchers have explored the depression mechanism of ZnSO 4 on sphalerite.

Flotation Reagent an overview ScienceDirect Topics

In the mining industry, cyanide is primarily used for leaching gold and silver from ores, but it is also used in low concentrations as a flotation reagent for the recovery of base metals such as copper, lead, and zinc. At many of these operations, cyanide treatment systems may be required to address potential toxicity issues in regard to the health of humans, wildlife, waterfowl, or

The Importance of pH in Flotation

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is
