Uranium Mining and Milling Wastes: An Introduction

In the early years of uranium mining after World War II, the mining companies often left sites without any clean up after the ore deposits were exhausted: often, in the United States, the mining and milling facilities were not even demolished, not to mention reclamation of the wastes produced; in Canada, uranium mill tailings were often simply

Uranium Mining and Extraction from Ore Robert B. Laughlin

21/03/2012· The need to find significant uranium deposits for mining has resulted in the development of a variety of survey techniques. However, the most common exploration techniques used for regional prospecting are aerial photography, aeroradiometry, the hydrochemistry of ground water, and gamma-ray surveys for identifying specific drilling sites.
