Acid Leaching of Uranium

 · Acid leaching has been used in the uranium milling industry since the midforties and has accounted for a majority of the production since that time. It is preferred over carbonate leaching because of its greater efficiency in recovering uranium. Consequently much research has been done on the factors which influence the kinetics of the oxidation of uranium, as well as those which influence ...

How is uranium made into nuclear fuel

The vast majority of nuclear power reactors use the isotope uranium235 as fuel; however, it only makes up % of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium235 concentration from % to between 3% and 5%, which is the level used in most reactors.

Uranium Mining Overview

Uranium Mining Overview. (Updated September 2021) In the last 60 years uranium has become one of the world's most important energy minerals. It is mined and concentrated similarly to many other metals. While uranium is used almost entirely for making electricity, a small proportion is used for the important task of producing medical isotopes.

 · Uranium Milling Process. After extraction, the ores from both open pit and underground mines require milling. Machines crush and pulverize the rocks into fine fragments. Processors first add water and then sulfuric acid or an alkaline solution to release uranium from the rocks. This produces uranium oxide (or yellow cake). Another processing plant then enriches this uranium further to .

Uranium Mining and Milling Wastes: An Introduction

In the most cases, sulfuric acid is used as the leaching agent, but alkaline leaching is also used. As the leaching agent not only extracts uranium from the ore, but also several other constituents like molybdenum, vanadium, selenium, iron, lead and arsenic, the uranium must be separated out of the leaching solution. The final product produced from the mill, commonly referred to as "yellow ...
