Explaining the Process of Froth Flotation
These collect in a froth heavily laden with sulphide particles. The gangue particles are not brought up by the bubbles, but remain in the mass of the pulp. This is the so-called froth flotation. Its variations, acid-froth, agitation- froth, and pneumatic-froth processes are discussed in detail later.

Phenomena in the froth phase of flotation — A review
The froth phase is one of the main components of froth flotation as it defines both the quality of the end product and overall efficiency. The performance of the froth depends on a number of sub-processes that interact in very complex ways, and it is a great research challenge to explicitly name the role of each of these sub-processes.

A hybrid feature selection method for production
The proposed FS method, mRMR-BSTA, is applied into the production condition recognition of gold-antimony froth flotation to reduce the redundancy and noise of the extracted 38 features. 5 efficient features are selected and the production condition recognition of gold-antimony froth flotation is categorized into 8 classes with high ...
[PDF] 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 the particles that remain completely wetted stay in the liquid phase.

Flotation of Nickel-Copper Sulphide Ore: Optimisation …
Abstract-Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a
