Describes where and how mineral deposits of this type are found, including chemical and mineralogical characteristics, as well as unsolved scientific questions surrounding their origin.
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.
Explains the geologic setting in which these deposits are found, with information about production and the processes used to extract these valuable mineral resources.
Reviews production, consumption, and reserves and important policies and regulations regarding production and trade of rare earths, including recently announced export quotas.
Estimates of known and undiscovered copper resources total nearly 60 million metric tons of copper. Iron resources in known deposits total 2200 million metric tons of ore. Twenty mineralized areas meriting further study were identified.
