In 1941, the Montana School of Mines bestowed on him the honorary degree of Doctor of Science for his research on flotation. The book "Principles of Mineral Dressing" authored by Gaudin is still the basic book for all mineral processing engineers. [7] He then assumed a professorship at MIT in 1939.
Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy. [1] Depending on the processes used in each instance, it is often referred to as ore dressing or ore milling .

Metallurgy derives from the Ancient Greek μεταλλουργός, metallourgós, "worker in metal", from μέταλλον, métallon, "mine, metal" + ἔργον, érgon, "work" The word was originally an alchemist's term for the extraction of metals from minerals, the ending -urgy signifying a process, especially manufacturing: it was discussed in this sense in the 1797 Encyclopædia ...
The Oubasi orogenic gold deposit in Southern Ghana is host to mineral resources of over 70 Moz Au at a grade of 7.39g/t or higher, with a past production of 32 Moz Au. [9] The deposit is located in the Birimian orogen, where gold mining is known to have taken place back to the 17th century, but modern industrial-scale mining began in 1897 by ...
Mineral processing operations are needed firstly to concentrate the mineral phases of interest and reject the unwanted material physical or chemically associated to a defined raw material. The process, however, demand about 30 GJ/tonne of metal, which accounts about 29% of the total energy spent on mining in the USA. [ 1 ]
In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the ...
In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with many types of mill. In dentistry, it is the result of mastication of food. In general medicine, it is one of the most traumatic forms of bone fracture.
