Ion Flotation Patentes

Ion Flotation - a metal recovery technique - European ...

Ion flotation can be performed by using a surfactant in combination with a different molecule – called a chelating agent, which can form a complex with the metal ion by chemically binding to it, so-called coordinating. The formed complex is then captured in the surfactant foam.

Ion flotation in environmental technology - ScienceDirect

1-1-1987· Ion flotation is most efficiently applied when the concentration of ion (col- ligend) is in the range of 10-5 to 10-3 M. Above these values the quantity of the product {ion-surfactant} formed is often inconveniently large, while below, the amount of surfactant present is insufficient to form a supporting foam and flota- tion is incomplete.

GB898213A - Process for the froth flotation of sulphide ...

Organopolysiloxanes are used in a process for the separation of sulphide ores from one another and from the gauge by flotation, the flotation being carried out in the presence of organopolysiloxanes and conventional collective or collector frothers. A suitable organopolysiloxane is a liquid polydimethyl siloxane and a suitable collector is axanthate, e.g. potassium ethyl xanthane.

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.

Mechanism of Selective Ion Flotation | SpringerLink

It has been determined that ion-water and cation-surface active anion interactions govern the ion flotation selectivity, when a sublate was not formed in the bulk solution. The flotation selectivity orders of anions were correlated with the experimentally-determined viscosity coefficients, whereas the flotation selectivity orders of cations were correlated with their ionic potential values.
