Oct 19, 2016 The most common type of reagents used for industrial mineral flotation are anionic in nature. They are made up of various types of fatty acids derived from animal and vegetable sources. Reagent selection is based on sampling the mineral and doing laboratory flotation to screen the type of reagent and its application for direct or reverse flotation.

Pergamon Press plc. 1992. - 343 p. ISBN 0-08-041864-3 This work provides a unique and authori ative review of sulphide mineral collector properties, their manufacture and use with specific ores. Special emphasis is placed on the different flotation mechanisms involved in particle capture of sulphide and non-sulphide minerals and the effect of antagonal mechanisms on reagent selection.
Strong ties to a broad range of equipment and flotation reagent suppliers ensure we have the most effective, practical, and innovative methods for mineral separation. Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores.
Also available as the InertGas design for use in coppermoly separation resulting in lower reagent consumption and eliminating the need for nitrogen supply. A simple and rugged construction make the Wemco 11 flotation mechanism extremely reliable and keeps your maintenance to a minimum.
2750 ml, giving a flotation pulp density of 30 wt. The reagents were all added 5 minutes before the start of flotation. The flotation gas was air at a flow rate of 8 lmin, producing 0.70 cms superficial air velocity. Froth depth of the order of 1 cm was scraped every 10 seconds during the test, and the concentrate was collected in trays.

deionised waters where flotation was inhibited by three water- recycles. Organic species such as thio-phosphates and carbamates released from residual reagents in water and inorganic species from tailing samples that dissolve were responsible for water quality and hence flotation kinetics. The impact of water type on borate ore flotation was
flowsheet, reagent scheme and process control requirements. In order to illustrate the generic factors involved both in evaluating flotation flowsheets and designing the flotation circuits the development of two sulfide flotation projects, Hellyer and Cadia Mines, is compared and contrasted in the Case Studies provided later in the paper.

The flotation time determined in laboratory flotation cells is a basis for design and construction of plant operating units. For coal, these times are between 5 and 10 minutes, these are known to be longer for ores and industrial minerals and for rougher flotation of difficult minerals can even be up to one hour.
A depressant reagent such as guar gum works to suppress the undesirable fraction and any remaining slimes, while amine collector reagents promote flotation of the desirable component. A number of other materials may be added during conditioning to improve process conditions as well.
