Uranium Mining and Milling Wastes: An Introduction

WASTE ROCK Waste rock is produced during open pit mining when overburden is removed, and during underground mining when driving tunnels through nonore zones. Piles of socalled waste rock often contain elevated concentrations of radioisotopes compared to normal rock. Other waste piles consist of ore with too low a grade for processing.

Extraction of uranium from solid waste containing uranium ...

Jun 01, 2014· Fig. 1 shows the points in the uranium conversion process where spent NaF adsorbents, sludgelike wastes, and residue wastes are generated. UF 4 was produced from a solution, in which yellow cake was dissolved as uranous ions in a reaction bath. A portion of UF 4, which could not be transported because of solidification, remained as a blockish residue waste in the reaction bath.

Uranium processing | Britannica

Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense ( 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.
