Froth Flotation - an overview ScienceDirect Topics

Typically three different types of chemicals are used in the froth flotation process: collector, frother, and modifier. First, the collector is added to the iron ore slurry to selectively coat the iron oxide particles, making the surface hydrophobic. The slurry then goes to a flotation cell, where air bubbles are generated using an impeller and aerator

Flotation Froth - an overview ScienceDirect Topics

Froth flotation is used for processing many types of ores, including cleaning coal fines (Harris Wheelock, 2008). The process is based on differences in the “wettability” of materials. Nonwettable materials are more susceptible to bubble attachment, the mechanism of separation, which is achieved by the addition of a frothing agent and injection of air

04/03/2005  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. It has been described as "the single most important operation used for the ...

5 Types of Phosphate Froth Flotation Process

Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite, calcareous phosphorite, and siliceous phosphorite according to the chemical composition of the minerals.The ...

A laboratory study was conducted to evaluate and compare the effectiveness of nine different frother types when used in a three-phase, continuously operating froth flotation system. The frothers included several that are commonly used in the industry (e.g., MIBC, 2EH, and F-1) as well as unique frother types (e.g., F-3). The tests were conducted in a 5-cm diameter laboratory flotation column ...

01/11/2008  On the practical side, arguments can be made that bubble size is a key driver through its contribution to bubble surface area flux (S b), and hence flotation kinetics (Gorain et al., 1998, Hernandez et al., 2003) and that once S b and froth depth have been established, concentrate overflow rate and grade from a cell are determined for a given system (including frother type). That is, the ...

2 Types of Froth Flotation Processes - Mining-pedia

2. Stage Froth Flotation Process. Stage froth flotation process is mainly because the ore has uneven disseminated grain size, which is necessary to be carried out grinding operation after a stage froth flotation process, that is known as the two-stage froth flotation process. By that analogy, this is multiple stage froth flotation.
