Uranium Mining and Milling Wastes: An Introduction

URANIUM MINES Most uranium ore is mined in open pit or underground mines. The uranium content of the ore is often between only 0.1% and 0.2%. Therefore, large amounts of ore have to be mined to get at the uranium. In the early years up until the 1960's uranium was predominantly mined in open pit mines from ore deposits located …

NRC: Conventional Uranium Mills

A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.

Influence of uranium mineralogy and lithology on the flowsheet A classification of uranium ores according to their metallurgical behaviour has been provided by Lunt and Holden1. The key minerals are identified as follows: Ores containing tetravalent uranium Tetravalent uranium has a low solubility in both dilute acid and carbonate solutions.

Concentration

The general flowsheet of uranium ore processing is composed by the following steps: crushing, screening, wet milling, alkaline or acid leaching, filtration-washing of the residue, uranium extraction by solvent or ion exchange resins, and chemical precipitation [1,2].

NRC: Uranium Recovery (Extraction) Methods

Uranium recovery involves one of the following extraction processes. In a conventional uranium mine and mill, uranium ore is extracted from the Earth, typically through deep underground shafts or shallow open pits. The ore is transported to a mill, where it is crushed and undergoes a chemical process to remove the uranium.

Uranium processing - Canadian Nuclear Association

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.
