flotation process invention

Flotation ore dressing Britannica

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

"Flotation Process"

The Flotation Process Until the invention of the flotation process, the extraction of metal depended upon being able to hand-pick the material in order to be economical. Taking copper as an example, previously, that meant that using low-grade ores with less than four percent metal content

History of Flotation Patents

This is the part of the subject of which we have heard the most; indeed, until recently the literature of the flotation process was closely identified with the records of patent litigation. That is why the scientific principles are as yet so little understood and the technology of the process has made such scanty progress. The aim of a patent specification is to disclose just enough to prove

Brief Introduction of Fluorite Flotation Process

The present invention provides a carbonate fluorite ore economic effective flotation separation method, especially for the high carbonate content of the flotation separation of fluorite ore. The key is to choose the carbonate minerals inhibitors acidified water glass processing drug measures in the conventional process conditions, carbonate

US4268380A Froth flotation process Google Patents

An improvement in the froth flotation separation of metallic sulfide mineral ores, particularly those ores bearing copper and molybdenum, in which a mercaptan collector is used in an earlier primary flotation stage, the improvement comprising the addition of activated carbon to achieve deactivation of the mercaptan collector prior to the component mineral separation stage, thereby providing

Froth flotation process Australia Innovates Powerhouse

The process is still being developed and improved upon. Within ten years 5.7 million tonnes of accumulated waste had been reprocessed with a value of 30 million pounds ($60 million). The froth flotation process for separating mineral ores was so much more efficient than previous methods it was soon adopted at metal mines worldwide.

Flotation process Inco Limited

The present invention has also been tested and found operable with ore pulps containing Px, Cp and Pn and in which the ore has undergone a natural or induced process of oxidative conditioning or leaching prior to or during flotation, such that the ore has been exposed to oxygen as well as to oxidation products of the sulfide ion such as sulfite
