Concentration of Ores

Explanation: In electromagnetic separation, the powdered ore is dropped over a conveyer belt moving around two rollers, one of which has an electromagnet in it. As the ore particles roll over the belt, the magnetic particles are attracted by the magnetic roller. As a result, two heaps are formed separately.

Methods of concentration of Ores – Gravity Separation.

Electromagnetic separation; As the name suggests, magnetised material, such as a magnet-equipped roller, is used for separating the unwanted particles to enrich the ore. The magnetic characteristics of the ore or the gangue particles are used for separation. The ore is powdered and is laid on a conveyor belt that passes through a magnetic roller.

Your Engineering Heritage: Thomas Edison's Legacy in …

By 1901 Edison had spent $2.9 million-equal to $78 million in 2014-making electromagnetic ore separation practical. At the end of the nineteenth century, he lived through an experience that the entrepreneurs extracting crude oil from Alberta's tar sands and the Bakken Shale Formation would find familiar.

Thomas Edison's Gamble with Resource Extraction

After spending over a decade in attaining technical and commercial success, he admitted defeat as even cheaper high yield ore around Lake Superior drove him out of business. By 1901 Edison had spent $2.9 million—equal to $78 million in 2014—making electromagnetic ore separation practical.

Manhattan Project: Processes > Uranium Isotope Separation

Actual separation of the uranium isotopes would occur in the vacuum tanks. Construction of the first racetracks at the Y-12 Electromagnetic Plant in Oak Ridge began in February 1943. A month later, a second stage was added to the process. In the first stage, the larger Alpha racetracks would provide enriched uranium-235 as feed material for the ...
