Technology advancement: A factor in increasing resource use
David R. Wilburn, Thomas G. Goonan, Donald I. Bleiwas
2001, Open-File Report 2001-197
The specter of mineral resource scarcity has been repeatedly raised as a concern because ever-growing populations with seemingly insatiable appetites for minerals place claims against a finite resource endowment. This report analyzes how technology has helped to ease resource constraints, and uses case studies of aluminum, copper, potash, and sulfur...
A simplified economic filter for open-pit mining and heap-leach recovery of copper in the United States
Keith R. Long, Donald A. Singer
2001, Open-File Report 2001-218
Determining the economic viability of mineral deposits of various sizes and grades is a critical task in all phases of mineral supply, from land-use management to mine development. This study evaluates two simple tools for estimating the economic viability of porphyry copper deposits mined by open-pit, heap-leach methods when only...

Iron and steel recycling in the United States in 1998
Michael D. Fenton
2001, Open-File Report 2001-224
Consumption of iron and steel scrap and the health of the scrap industry depend directly on the health of the steelmaking industry. The United States, as well as most of the world, is expected to consume increasing amounts of scrap as a steadily increasing population demands more steel products. World...

Eagle Mountain Mine: Geology of the former Kaiser Steel Operation in Riverside County, California
Eric R. Force
2001, Open-File Report 2001-237
This investigation of the Eagle Mountain Mine area, though cursory, revealed new structural, alteration, and stratigraphic relations. Eagle Mountain ores were previously an important source of iron to the western U. S. Ore (where fresh) is magnetite-pyrite rock forming two stratabound horizons virtually continuous for 11 km. Gneissic basement rocks are...
Metal loading assessment of a small mountainous sub-basin characterized by acid drainage -- Prospect Gulch, upper Animas River watershed, Colorado

2001, Open-File Report 2001-258
strongly affected by natural acidity from pyrite weathering. Metal content in the water column is a composite of multiple sources affected by hydrologic, geologic, climatic, and anthropogenic conditions. Identifying sources of metals from various drainage areas was determined using a tracer injection approach and synoptic sampling during low flow conditions on September 29, 1999 to determine...
