Notes On The Development Of The Flotation Process For Concentrating Copper And Iron Sulphide Ore, Holman Thompson Marshall

Bachelors Theses

"The first flotation machines was installed at the Magna Mill of the Utah Copper Co. in August and September, 1914. The outbreak of the war in Europe having made necessary the shutting down of the Arthur Mill of the same company, the flotation plant was installed at Magna for the purpose of carrying on experiments which had been in process at Arthur. Enough experimentation had been done with the small laboratory machine at Arthur, and results obtained were favorable enough to warrant the installation of a full size Janney machine"--page 1.
