Flotation Of Valuable Minerals

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Flotation - Mineral Processing & Metallurgy

The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations ...

In addition, the mineral recovery estimation in rougher circuits strongly depends on the feed and tail grades, which typically present low values and are more disturbed by sampling and assays errors. In this paper, the collection of valuable minerals in different flotation plants was studied by using top-of-froth (TOF) measurements.

Flotation - ScienceDirect

Flotation relies on the surface of the valuable mineral being hydrophobic, while the surface of the gangue minerals is hydrophilic. When the three phases, solid, liquid and gas, are in contact, an equilibrium is established between the solid–air, solid–liquid and liquid–air interfacial tensions, γ SA , γ SL and γ LA as shown in Figure 18.1 .

A Brief Review of Pulp and Froth Rheology in Mineral …

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
