Groundwater Of The Spiritwood Lake Area, Stutsman County, North Dakota, Frank J. Schulte Jan 1972

Groundwater Of The Spiritwood Lake Area, Stutsman County, North Dakota, Frank J. Schulte

Theses and Dissertations

The Spiritwood Lake study area is in a generally undulating to rolling glacial plain 17 miles north and east of Jamestown, North Dakota. Spiritwood Lake is about 50 feet below the surface of the bedrock plain in a former melt-water channel. In the study area, glacial drift unconformably overlies the Pierre Shale, the youngest pre-Pleistocene sediment. The boundary between the two units is marked by a zone of shattered Pierre Shale. The top of this shattered zone forms a plain of moderate relief which probably was the preglacial surface of the study area.

Two large valleys can be distinguished in …

Collector-Depressant Equilibria For The Flotation System Potassium Ethyl Xanthate-Potassium Cyanide-Molybdenite, Connell Bolton Roberts Aug 1952

Collector-Depressant Equilibria For The Flotation System Potassium Ethyl Xanthate-Potassium Cyanide-Molybdenite, Connell Bolton Roberts

Theses and Dissertations

This dissertation involves a study of the collector-depressant equilibria of the flotation system potassium ethyl xanthate-potassium cyanide-molybdenite, based upon mineral-air bubble contact measurements made by a modified captive bubble technique. The Cook theory of single site free acid adsorption is used to interpret the data. The standard free energies of adsorption of ethyl xanthic acid and hydrocyanic acid on molybdenite are calculated.
