The treatment can be applied to the alkaline carbonate leach solution of uranium contaminated with molybdenum as it is pumped from a recovery well and before it is fed into an ion exchange extraction column to remove the uranium. This removes the molybdenum from the leach liquor before it is recycled to the well and thus prevents the build up of molybdenum which would otherwise occur with resultant decomposition of the hydrogen peroxide used as an oxidant.

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 near the surface.
