Uranium — How Is It Mined?

Uranium — How Is It Mined?

Milling. Uranium milling involves extracting uranium from mined ore. The ore is crushed into sand size particles and the uranium is leached out. The uranium then is precipitated out of the leaching solution and dewatered, dried, and packaged. Through the extraction process, uranium is concentrated into a product referred to as "yellowcake."

The pump in the production well collects the uranium laden water and sends it to the processing plant where the uranium is removed by ion exchange. The water is then refortified with oxygen and baking soda and sent back to the ore zone to recover more uranium. The native groundwater continues in this cycle until uranium extraction is complete.

Uranium milling After mining, uranium ore is transported to a nearby mill for processing. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock. The uranium is now part of a liquid solution, which is then separated from .

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.
