The success of the London operation was also integral to the local economy. Much of the population worked for or sold goods and supplies to the mining operation. The mine and mill were large factors in the establishment the London Junction (now Alma) stop, carrying ore and tailings from the mine to Denver on the Denver & South Park Railroad.

A mining operation is an industrial entity whose objective and function is to extract from the earth crust a metal or other substance of economic value and process it to a stage where it can be sold for further transformation. There are several types of mining operations. For mining and milling of uranium a distinction is made between ...

At the Cluff Lake uranium mine and mill in Canada, in phase 1 operations high-grade ore was fed to a gravity concentration plant with jigs and vibrating tables. The concentrate averaged over 30% U (Schnell and Corpus, 2000). The gravity concentrator rejects were stored and retreated later (see Section 6.5.1).

The challenge to maximize resource efficiency requires the optimal use of all products leaving a mine—not only ore but also waste products—and calls for contributions from and cooperation with every discipline involved as efficiently as possible. These interdisciplinary and transdisciplinary interactions between practitioners and scientists are also an act of …
