Abandoned Uranium Mines Project Atlas Project Overview
The Navajo Nation is located on the Colorado Plateau and encompasses over 25,000 square miles across Arizona, New Mexico, and Utah. The distinctive physiography of this region has resulted in a major mining area for uranium. The Navajo Nation includes intensely dissected rocky regions and has elevations that range from about 3,000 feet to slightly over 10,000 feet. The region is known for a wid...
متن کاملA system for volumetric robotic mapping of abandoned mines
This paper describes two robotic systems developed for acquiring accurate volumetric maps of underground mines. One system is based on a cart instrumented by laser range finders, pushed through a mine by people. Another is a remotely controlled mobile robot equipped with laser range finders. To build consistent maps of large mines with many cycles, we describe an algorithm for estimating global...
متن کاملGeoenvironmental Characterisation of Heap Leach Materials at Abandoned Mines: Croydon Au-Mines, QLD, Australia
Heap leaching is a well-established metallurgical technology which allows metal recovery (e.g., Au, Cu, U) from low-grade ores. However, spent heap leach materials remaining at abandoned or historic mine sites may represent a potential source of contamination. At the Croydon Au-mines, heap leaching operations (1984–1985) were performed on mineralized rhyolites hosting sulphides including pyrite...

متن کاملHeavy metal pollution associated with an abandoned lead-zinc mine in the Kirki region, NE Greece.
The "Agios Philippos" mine in the Kirki region (NE Greece) has been abandoned in 1998 after half a century of ore exploration without a reclamation or remediation plan. This article aims at elucidating the potential environmental risks associated with this site by quantifying pollution in tailing basins, stream waters, stream sediments and agricultural fields. Concentrations of heavy metals in ...
