Geothermal Development Plan: Pima County (open access)

Geothermal Development Plan: Pima County

Pima County is located entirely within the Basin and Range physiographic province in which geothermal resources are known to occur. Continued growth as indicated by such factors as population growth, employment and income will require large amounts of energy. It is believed that geothermal energy could provide some of the energy that will be needed. Potential users of geothermal energy within the county are identified.

The Occurrence of Uranium in the Diamond Head Group, Sierrita Mountains, Pima County, Arizona (open access)

The Occurrence of Uranium in the Diamond Head Group, Sierrita Mountains, Pima County, Arizona

Abstract: The Diamond Head droup area is entirely igneous. Tight fractures in alaskite and granite, which have been altered by heiratite and kaolinization contain narrow seams and very locally,pods of sooty uraninite. A greater percentage of the structures in the area strike about east-west and dip steeply to the north, while the radioactive structures have similar strike, they dip steeply to both the north and the south. A drift has been driven on a mineralized structure far enough to ascertain that the general character of the mineralization is very narrow seams. Many such seams exists but are scattered throughout the area.

Innovations in Copper Leaching Employing Ferric Sulphate-Sulphuric Acid (open access)

Innovations in Copper Leaching Employing Ferric Sulphate-Sulphuric Acid

From Introduction: "The Bureau of Mines has attempted to develop a cheap and efficient solvent that would especially meet the requirements of smaller plants. (See Bibliography). A method of producing this solution from sulphurous products and waste liquors was developed by the bureau and tried successfully on a test-plant scale at the Southwest Experiment Station in cooperation with the department of mining and metallurgy, University of Arizona, Tuscon, Ariz."
