Uranium Mining and Fuel - Nuclear Power Info

The Mining Process: There are three main methods of mining uranium, or any mineral for that matter. The first is open pit mining, also known as strip mining. It is a cheap mining method and also an extremely environmentally damaging process, as large swaths of earth are stripped away to reveal the mineral deposits.

uranium processing Britannica

uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.
