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.

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 …
