Flotation - Mineral Processing
Flotation is also used to remove impurities before hydrometallurgical treatment (ie, carbon pre-flotation) to purify low-sulfide and refractory ores for further processing. Flotation is considered to be the most cost-effective method of concentrating refined gold and is often used in conjunction with flotation

Flotation ore dressing Britannica
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to

Flotation - Mineral Processing Metallurgy
Jan 11, 2016 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 ...

Mineral Processing Froth Flotation
Jun 22, 2015 Froth Flotation is a mineral processing process achieving solid-solid separation by taking profit of the chemical attribute leading to the possibility of selectively controlling the relative surface hydrophobicities of the various components mixed in an aqueous medium.. Froth flotation is the most common industrial process based on this approach. The term surface hydrophobicity refers to the ...

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.

Jan 20, 2021 “The single most important method used for the recovery and upgrading of sulfide ores”, that’s how G. J. Jameson described the froth flotation process in 1992. And it’s true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are increased by ...
