Hence, they are also called the enemies of the Collectors. They increase the Selectivity of flotation, by preventing one mineral from flotation while allowing another mineral to float unrestricted. Depressants can be classified into two categories. Inorganic depressants such as Sodium cyanide, Zinc sulphate etc.

sphalerite and pyrite in the lead flotation circuit. As explained in Chapter 2, cyanide dosages of 150-180 g/t NaCN are often used at the plant at the natural pH of about 8.5±0.3. Despite the high dosage of cyanide used in the lead flotation circuit, it is assumed that approximately 1250 tons of zinc is lost every year in the lead

Oxide and Reverse Flotation | SGS

In reverse flotation, proper reagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting). Aeration is added through spargers at the bottom of the flotation cell. The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow.

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

It differs from other recovery circuits in that most of the gold recovered by gravity would be recovered in any case by the circuit downstream, be it flotation or cyanidation. The economic justification of gravity is therefore based on small margins (for example, a net smelter return of gravity gold of 99%, as opposed to 94% for flotation).
