Flotation Process Invention

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, stone 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.

History of Flotation Patents - Mineral Processing & Metallurgy

History of Flotation Patents. As the flotation process of today is essentially that of making a mineral-buoying froth in modified water, it is not necessary for me to make further reference to the patents granted for the use of purely surface-tension effects. It would seem permissible also to omit further consideration of the bulk-oil methods, but,...

Who invented the flotation process - Answers

The induced air flotation machine was invented by William Fagergren in the 1930s in the Salt Lake Valley of Utah. Induced air means that the rotor for the froth flotation machine draws in...

US5106489A - Zircon-rutile-ilmenite froth flotation ...

A process has been discovered for froth flotation by manipulating the surface charges of dry plant tailings. Conditioning reagents, sulfuric acid to lower the pH; stone starch to coat the minerals to be depressed; sodium fluoride to activate the minerals to be floated; and amine to float the activated minerals, are used in the flotation process.

The flotation method of separation of multicomponent mixtures

The invention relates to ferrous metallurgy, in particular to a method for separation of copper-Nickel pantanaw on copper and Nickel concentrates, can be used also in mining and processing industries to flotation enrichment of natural minerals. The technical result is an improvement of the gas-filling of the pulp in photomachine fine gas bubbles.
