Utilization of geothermal energy in the mining and processing of tungsten ore. Quarterly report

Description: The status of the engineering and economic feasibility study of utilizing geothermal energy for the mining and processing of tungsten ore at the Union Carbide-Metals Division Pine Creek tungsten complex near Bishop, Calfironia is reviewed. Results of geophysical data analysis including determination of assumed resource parameters are presented. The energy utilization evaluation identifies potential locations for substituting geothermal energy for fossil fuel energy using current technology. Preliminary analyses for local environmental and institutional barriers to development of a geothermal system are also provided.

Utilization of geothermal energy in the mining and processing of tungsten ore. 2nd quarterly report

Description: The completed geochemical analysis of groundwater in the Pine Creek area for evaluation of the geothermal potential of this location is presented. Also included is an environmental constraints analysis of Pine Creek noting any potential environmental problems if a geothermal system was developed onsite. Design of a geothermal system is discussed for site-specific applications and is discussed in detail with equipment recommendations and material specifications. A preliminary financial, economic, and institutional assessment of geothermal system located totally on Union Carbide property at Pine Creek is included. (MHR)

Commercial production of ethanol in the San Luis Valley, Colorado. Final Report

Description: The purpose of this study is to assess the commercial feasibility of producing between 76 and 189 million liters (20 and 50 million gallons) of ethanol annually in the San Luis Valley, Colorado using geothermal energy as the primary heat source. The San Luis Valley is located in south-central Colorado. The valley is a high basin situated approximately 2316 meters (7600 feet) above sea level which contains numerous warm water wells and springs. A known geothermal resource area (KGRA) is located in the east-central area of the valley. The main industry in the valley is agriculture, while the main industry in the surrounding mountains is lumber. Both of these industries can provide feedstock for the production of ethanol.

The San Luis Valley is located in south-central Colorado. The valley is a high basin situated approximately 2316 meters (7600 feet) above sea level which contains numerous warm water wells and springs. A known geothermal resource area (IGRA) is located in the east-central area of the valley. The main industry in the valley is agriculture, while the main industry in the surrounding mountains is lumber. Both of these industries can provide feedstocks for the production of ethanol.
