Preliminary Construction Of A Photo-Electric Cell Concentrator, Stanley S. Williams Jun 1931

Preliminary Construction Of A Photo-Electric Cell Concentrator, Stanley S. Williams

Bachelors Theses and Reports, 1928 - 1970

The separation of the valuable portion from the waste portion of an ore is an individual problem for every ore. However, the various methods for accomplishing this end, more or less classify themselves by the physical properties of the constituents of the ore. Most of the properties of minerals have been utilized in some way or other to affect the separation of the valuable from the invaluable parts. Practically nothing has been done so far with color and luster to attain this purpose.

It is believed that the photo—electric cell could also be used in concentrating a certain class ...


Age Relationships Of Ore Deposits Of Southwestern Montana (A Microscopic Study), Charles R. Trueworthy Jan 1931

Age Relationships Of Ore Deposits Of Southwestern Montana (A Microscopic Study), Charles R. Trueworthy

Bachelors Theses and Reports, 1928 - 1970

Although considerable work has been undertaken by some prominent geologists, the best known of which is that of Paul Billingsley and J. A. Grimes', in investigating the ore deposits of the Boulder Batholith and surrounding area, there has not been any complete microscopic investigation of these deposits, as a whole, published in the literature. With this in mind it was suggested to the writer by Professor Paul A. Schafer, of the Montana School of Mines, that a microscopic study of the ores of this region would be a worthwhile geologic problem.

It was thought that the mineral association and the ...


A Preliminary Study Of The Separation Of The Copper Sulfides From Sphalerite And The Effect Of Certain Reagents On Some Of The Pure Copper Minerals In Synthetic Mixtures, Gailen T. Vandel Jan 1931

A Preliminary Study Of The Separation Of The Copper Sulfides From Sphalerite And The Effect Of Certain Reagents On Some Of The Pure Copper Minerals In Synthetic Mixtures, Gailen T. Vandel

Bachelors Theses and Reports, 1928 - 1970

The problem of separating the copper sulfide minerals from sphalerite, in copper - zinc ores, has been a difficult one. This is largely due to the lack of adequate research and the small amount of data obtainable on the behavior of copper and zinc sulfide minerals in flotation circuits.
