Geology 63: Geological Report of Senior Field Trip

The field work was conducted in areas adjacent to White­hall, Montana, as has been the custom for the past several years. Instruction in the proper use of the telescopic and open sight alidades, and the Brunton compass for surveying geologic features was given. Advantages of pacing and speed­ometer mapping were pointed out and used.

Leaching of Low Grade Rhodochrosite

Although there are many uses for manganese today, none of them approaches its importance as a deoxidizing agent in the manufac­ture of steels. Without manganese the steelmaking in­dustry would be very seriously handicapped. The metal­lurgy of manganese has been developed around the high-grade ores, and unfortunately, our reserves of high-grade ores are very limited.

Concentration of Manganese Dioxide from Philipsburg, Montana

Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company ac­counted for 90 percent of the total shipments of mangan­ese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.
