Dictionary of Mining, Mineral, and Related Terms by American Geological Institute [Repost]

This new edition, containing 28,500 terms, incorporates the technological developments and environmental regulations that have changed the minerals industry so dramatically. It is the culmination of a 5-year effort incorporating not only standard mining-related terms but also terms in peripheral areas, such as the environment, marine mining, leaching, pollution, automation, health and safety. Many of these terms now have a legal definition based on law or regulation.
