Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
Defines what a mineral deposit is and how a mineral deposit is identified and measured, how mineral resources are extracted, and how a mine site is reclaimed; how minerals are processed; and how we use minerals in everyday life.
Explains the geologic setting in which these deposits are found, with information about production and the processes used to extract these valuable mineral resources.
New discoveries and modernized extraction methods prompted renewed interest in gold deposits in this part of central Alaska, prompting a variety of studies described here.
Since the beginning of the 20th century, the types and quantities of raw materials used by U.S. manufacturers and consumers have changed over time. This fact sheet quantifies the amounts of those materials used, other than food and fuel.
The Marcellus shale is a black shale unit in the eastern US. It has economic use as a source of natural gas. Environmental concerns arising from the process of exploiting this resource include water supply and wastewater disposal.
