The purposes of this report are 1) to shed light on abandoned mining sites and their impacts on public lands; 2) to highlight the accomplishments of the BLM, the Forest Service, and project partners in addressing abandoned mine lands (AML) problems; and 3) to describe the outlook for future AML reclamation efforts. Examples throughout the report offer insight into the environmental, health, safety, and economic effects often associated with these sites and illustrate the lasting and acid mine drainage leaching from the positive impacts of reclamation activities on formerly mined lands.

This comprehensive book contains contributions from specialists who provide a complete status update along with outstanding issues encompassing different topics related to deep-sea mining. Interest in exploration and exploitation of deep-sea minerals is seeing a revival due to diminishing grades and increasing costs of processing of terrestrial minerals as well as availability of several strategic metals in seabed mineral resources; it therefore becomes imperative to take stock of various issues related to deep-sea mining. The authors are experienced scientists and engineers from around the globe developing advanced technologies for mining and metallurgical extraction as well as performing deep sea exploration for several decades. They invite readers to learn about the resource potential of different deep-sea minerals, design considerations and development of mining systems, and the potential environmental impacts of mining in international waters.
