It is well stated by Hoover in his book, ‘Concentrating Ores by Flotation,’ the first authoritative publication on the subject. Second: There is a parallelism between certain electro-static characteristics and the flotation properties of ores, as will be explained.

Although the subject of testing for flotation has been well presented in T. Hoover’s book on ‘Concentrating Ores by Flotation, there is need of later information on this timely subject.

Wills' Mineral Processing Technology provides practising engineers and students of mineral processing, metallurgy and mining with a review of all of the common ore-processing techniques utilized in modern processing installations.

Now in its Seventh Edition, this renowned book is a standard reference for the mineral processing industry. Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.

For some oxidized iron ores, the selectivity of high-intensity and high-gradient magnetic separators may not be as good as other methods. Nevertheless, they can reject most of the gangue minerals if they are used at the roughing stage. This will significantly reduce the amount of ore required to be “cleaned” by flotation or gravity separation.

Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations.

British metallurgist, one of the originators of the froth flotation process for concentrating ores preliminary to the extraction of metal (with H.F.K. Picard, U.S. patent No. 6 Nov ). In this latter method, crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents.
