AMIT 145: Lesson 5 Froth Flotation

Froth flotation is a physico-chemical separation process Separation is principally based on differences in surface hydrophobicity However, particle size and density have a significant impact Initial flotation patent and application was developed for graphite by the Bessel brothers (1877) Similar to graphite, coal is naturally hydrophobic.

Flotation

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.

Separation of WEEE plastics resorting gravity separation

To try achieving a successful separation of similar specific weight plastics, froth flotation was applied Similarly to the froth flotation of minerals, the physical separation of the plastics is achieved by creating an adequate physic-chemical environment to carry on a.

US5171428A

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO 3 - ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings.

Copper Flotation

Ore Concentration by Froth Flotation Remember that only 067% of the ore is copper The copper minerals and waste rock are separated at the mill using froth flotation.
