Joint Planes in the Rhyolites of the Butte District, Montana

The problem herein discussed deals with the pointing planes found in the area of rhyolite located in the northwestern portion of the Butte District. The question to be determined was whether or not the pointing planes in the rhyolites could be class­ified with the Butte Ore fissure systems.

A Microscopic Study of some Volcanic Rocks in the Vicinity of Butte

The rhyolite rocks in the vicinity of Big Butte present a very interesting, though complicated study. It seems that no extensive or conclusive work has ever been done upon these extrusives. I have found that the rhyolites present a very interesting problem, especially microscopically, and that no doubt an intensive study along these lines will solve the problems concerning age relations of different flows and origin of the magma that produced the material for emanations.

Leaching Copper Minerals in the Butte District

The history of mining in Butte is woven about three of our principal metals. The gold placers first attracted the attention of miners in 1863, and reached their peak production in 1867. Silver was the second metal mined, and this operation required the erection of large mills with a consequent increase in mining activity that made the district a prominent producer. Although the presence of copper in the silver ore had been known, the credit for the first development of the copper veins is due Senator W. A. Clark. The original Colusa, Mining Chief, and Gambetta claims were developed to 1872. The ore was freighted by wagon trains 400 miles to Corrine, Utah, thence by rail eastward, some of it going to Swansea, Wales. The cooper production of the "richest hill on earth" has mounted to ten billion pounds.

Geology and Ore Deposits of the Butte-Highland Gold Mine.

The Butte-Highland mine is situated at the head of Basin Creek, in the Highland mining district, Silver Bow County, about 14 miles south of Butte. The tunnel portal and present surface plant are at an elevation of about 7350 feet above sea level, facing westward across the head of Basin Creek valley. The "ghost" mining town of Highland lies a mile to the east, near the forks of Fish Creek. Access to the mine is obtained at present from Beaudine's siding, 12 miles west. The property may also be reached, with difficulty, over poor roads from Limekiln hill, or from Moose Creek.

Organic Wastewater Chemicals in Silver Bow Creek - Butte to Warm Springs Ponds

The purpose of this study is to detail and analyze the distribution, concentration, and loads of 5 organic compounds along Silver Bow Creek in Butte, Montana from the Municipal Wastewater treatment plant to the Warm Springs Ponds. The chemicals analyzed include Carbamazepine (pharmaceutical), Miconazole (fungicide) and three antibiotics – Sulfamethoxazole, Thiabendazole, and Ciprofloxacin. This project begins a 2 year study to analyze 6 additional compounds (11 compounds total), to develop an effective method to detail and analyze OWCs using Mass Spectrometer/Liquid chromatography system, and to aid in assessment of aquatic health and ongoing restoration work. The EPA method 1694 was used for analysis

Relationships of Manganese Minerals in the Butte District

The use of manganese in the steel industry as a deoxidizing and desulfidizing agent makes it a necessity in modern industry, while the various alloy steels using manganese for the quality of toughness are also indispensable. Manganese is also used in the manufacture of such various articles as battery cells, paints and glass.

The Recovery of Zinc from Butte Mine Waters

Very little work has been done towards the recovery of zinc from mine water because the zinc content of the water is generally low. As different from copper, which can very easily be replaced by iron in any of its solutions, zinc is very high up in the electro-chemical series and so the few metals above zinc, most of which are rare and hence expensive, cannot be used to replace zinc from its solution.

Some Leaching Characteristics of the Butte Rhodochrosite

With the increasing importance of manganese in the metallurgical fields of today and tomorrow, ex­tensive work along the lines of its successful ex­ploitation has been accomplished by many investiga­tors. Since tie current world situation has shut off most of our supply of high-grade manganese ores from foreign sources, the low-grade domestic deposits have entered the fields of investigation very rapidly.
