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.

6.2 Depression of Sulfide Minerals With Cyanide. The depressing action of cyanide on pyrite during froth flotation is well known (Sutherland and Wark, 1955) and is widely exploited on many flotation plants to selectively separate copper minerals from pyrite. Depression of pyrite by cyanide during froth flotation appears to take place in solutions containing free cyanide, ferro/ferri cyanide

Flotation of water-soluble mineral resources ScienceDirect

19/11/2004· The most efficient and selective method of saline minerals mechanical separation is by flotation. Potash ores were first processed in the 19th century by the hot leaching method, with further crystallization of potassium salts from saturated saline solutions. This method has been used to this day.

Froth Flotation Metallurgist & Mineral Processing Engineer

The most widely-used collectors in sulphide mineral flotation are the xanthates or thiocarbonates. These reagents were developed in the 1920's and played a major role in the spread of flotation throughout the world. Hydrocarbon chain length is from: ethyl C2, propyl C3, butyl C4, amyl C5 to hexyl C6. They are classified as Anionic reagents.

A Practical Method of Approach to the Problems of Mineral

Response of a mineral to anionic and cationic flotation reagents varies with the nature of the mineral and the particle size. A rule is deduced for the selection of the correct type of reagent, which leads to a simple method of testing ores to determine the possibility of separating the constituents by flotation.

Froth Flotation Metallurgist & Mineral Processing Engineer

Froth Flotation Froth flotation is one of the most versatile and flexible of all mineral separation processes. Reasonable results are fairly easy to obtain but outstanding performance from a circuit requires constant attention and good understanding of the process and ore. Some of the variables that affect the operation and control of a flotation process are classified as follows: The tendency

Cyanides are the most commonly used in the selective flotation of Lead-Copper-Zinc and Copper-Zinc systems as Depressants for Sphalerite and pyrite ores. An eg. of the Cu-Zn system can be considered to understand the action of a Depressant, The Cu ions present in the mineral leads to unintetional activation of the Sphalerite (i.e. Zn mineral) and thereby preventing selective flotation. Hence

Laboratory Flotation Testing An Essential Tool for Ore

valuable mineral should be significantly higher than the flotation rates of the gangue minerals in the ore. This is often referred to as ‘maximising the selectivity’. Laboratory batch flotation, in which a 1 2 kg sample of ore is floated using a standard set of operating conditions, is the standard technique used to assess ore floatability. Traditionally these tests have been performed
