A Study of the Differential Seperation of Galena and Sphalerite

The smelting of complex lead ores is a difficult operation, especially when they contain considerable amounts of iron and zinc. When these ores are smelted, all of the zinc, which is valuable and well worth recovering, goes into the slag. With the advent of the flotation processes, and the ability of these processes to concentrate the lead and zinc minerals into separate products, the smelting of complex lead ores was to a great extent simplified.

The Chromite Deposits of Stillwater and Sweetgrass Counties, Montana

In writing this report, two objects were kept in mind, (1) to explain, if possible, the origin of the chromite deposits found in Sweetgrass and Stillwater Counties, and (2) to bring up to date all information on these deposits which had thus far been available. The work done consisted of study of the rocks and ores of the area under the microscope, both as thin sections and as polished sections, practically all of which was done at the Montana State School of Mines, during the school year of 1928 - 1929. The rock specimens and much information as to their locations and probable compositions were obtained from Mr. P. F. Minister, of the East Butte Copper Company. United States Geological Survey Bulletin 725-A, Deposits of Chromite in California, Oregon, Washington, and Montana, and the unpublished report on the Chromite deposits of the Boulder River, prepared by Prof. C. H. Clapp of the University of Montana, were frequently referred to and considerable material was drawn from them. The map of the Boulder River area is from Clapp's report.

Building Up: A history of Montana Tech Library 1900 - 2006

This paper traces the history of the Library of the Montana State School of Mines from its inception in 1900 to 2006. The history includes sketches of the library directors over 106 years, and the library’s various campus locations and emerging collections and services.

Geological Report of Summer Field Trip 1928

The object of this trip and report was to familiarize the students of the Montana State School of Mines with methods of taking and mapping surface and undergound geology. All surface geology was mapped by means of plane table and alidade, and undergound work by means of Brunton compass and taps. The senior class of the Montana State School of MInes under the supervision of Dr. E.S. Perry performed the work, which covered an area in Madison County including South Boulder Creek, near Jefferson Island, the Silver Star Mining District, and the Alameda Mine, near Virginia City.
