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 removed, while ...

Cinnabar is HgS which is sulphide ore for mercury. Therefore the correct option is A. Note: Only sulphide ores can be used for the froth flotation process. This is because the oil used for wetting the ore is pine oil and it can wet only the sulphides. It cannot wet any other ore and so the process cannot be used for other ores.

Froth floatation is a surface chemistry based selective concentration process generally applicable for dressing or concentrating sulphide ores. In other words, only the ore particles are wetted by the froth whereas the gangue particles are not. Once wetted, the ore particles rise to the top and they could easily be skimmed off.

Froth Floatation Process - The purpose of this process is to extract gangue from sulfide ores. The ore is pulverized and mixed with water to form a suspension. Collectors and Froth Stabilizers are added to this. Collectors like pine oils, fatty acids, etc. boost the metal part of the ore's non-wettability, allowing it to form a froth.
