Effect of carbon on Cu/Pb/Zn flotation. Froth Flotation
Froth Flotation (Sulphide & Oxide) Normally the best way to deal with naturally floating carbon is by pre-flotation. This pre-flotation process is described in the papers listed below: This is why the circuits were redesigned with a pre-flotation cleaning circuit with froth washing to minimise the losses of the valuable minerals andFroth Flotation (Sulphide & Oxide),Soda ash is often used in the flotation of non-sulphides such as scheelite. If you have a source of carbon dioxide (e.g. nearby gas well or off-gas from a power generator) would be cheaper than using soda ash. But great to hear about a gaseous application at least carbon dioxide doesn't load the solution with cations such as sodium.

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 Application of compound reagent H511 in the flotation,The froth property test indicated that the flotation pulp treated by the H511 had great froth stability due to the effect of cyclohexanol in H511. The flotation showed that the carbon removal rate of H511 was approximately 60 % higher than that of the diesel/sec-octyl alcohol.
