A flotation cell is a vital piece of equipment used in the mineral processing industry to separate valuable minerals from waste material through the process of froth flotation.
For instance, a wet high-gradient magnetic separator was investigated for the separation of pyritic sulfur from Egyptian coal (Ibrahim et al., 2016), and the separation of pyritic sulfur from ultra-fine coal was assessed in another study using pyrolysis and a wet high magnetic separation procedure (Yassin et al., 2022).
In this study, OBHA was used as collector for the flotation separation of fluorite and calcite. Under a natural slurry pH environment, the recovery of fluorite reached 80 % while calcite recovery was less than 5 % with 3 × 10 −4 mol/L OBHA. The flotation separation of fluorite from calcite can be achieved without the addition of depressants.

1. Introduction. The importance of flotation, as a separation process, to the economy of the whole industrial world is considered to be enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and …
Liu et al., 2007 examined the effect of dry and wet grindings on coal flotation separation for coarse and fine particles (−600 and −75 µm). Their results showed lower flotation efficiency for dry ground samples in comparison with wet ground ones. The differences between flotation efficiency for dry versus wet ground feeds were greater for ...

Hoods. Manufactured with radial veins, Multotec hoods include shaft protection, rotors, mounting nuts and protector caps.
Flotation machines, in general, may be categorized into four different classes: (i) mechanical or con-ventional cells; (ii) energy-intensive pneumatic cells; (iii) column cells; and (iv) froth separators. Of these, mechanical otation cells have dominated the min- …
Due to the inherent hydrophobicity that is the characteristic of a vast majority of plastics, changing selectively the surface characteristics of specific plastic from hydrophobic to hydrophilic should be achieved before flotation separation of plastics, namely the former method shown in Fig. 2.A major difficulty in plastics flotation lies in finding …
It is difficult to separate spodumene and albite by flotation with calcium ion as activator.
