This report is the result of an extensive literature search to determine the state-of-the-knowledge regarding environmental impacts from quarrying carbonate rocks in karst formations to better use of karst resources in sustainable ways.
Mines, mineral processing facilities, and petroleum facilities as well as information on location, operational status, and ownership in Cuba, as well as current status of known mineral industry projects and trends in the industry there.
Extensive discussion of the production and consumption of Tantalum. Production shifted over the years so that a much larger proportion of world supply now comes from Rwanda and the Democratic Republic of the Congo.
Links to Spectroscopy Lab projects to identify and map materials through spectroscopic remote sensing (imaging spectroscopy, hyperspectral imaging, imaging spectrometry, ultraspectral imaging, etc) on the Earth and in space.
Describes organizational process and field study used to estimate production capacity (mostly by artisanal miners) in the parts of the country likely to contain diamonds. We estimate a production capacity of 600,000 carats per year.
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.
