Milling and Processing - How Uranium Mining Works ...

At the mill, uranium ore undergoes a variety of changes to turn it into a finished product: uranium powder, also known as yellowcake. The milling process is so important that the U.S. Atomic Energy Commission has helped mines establish mills close by to make it easier to process uranium ore and quicken the production of yellowcake [source: Amundson ].

Radioactive Waste From Uranium Mining and Milling US

Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining. The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.

Uranium Mining and Milling Wastes: An Introduction

In the early years of uranium mining after World War II, the mining companies often left sites without any clean up after the ore deposits were exhausted: often, in the United States, the mining and milling facilities were not even demolished, not to mention reclamation of the wastes produced; in Canada, uranium mill tailings were often simply dumped in one of the numerous lakes.

Occupational exposure: Uranium mining and milling

What do I need to know? Exposure to ionising radiation in the mining and milling of uranium ores can come externally from gamma radiation emitted from ore and process materials or internally from the inhalation of radon decay products, uranium ore or uranium product dust. Internal exposure is also possible through the ingestion of materials.

The long term stabilization of uranium mill tailings

Large volumes of low activity milling residues, such as mill tailings, are produced – sometimes exceeding millions of tonnes at a single uranium mining/milling facility, in particular, when uranium is only a by-product. The common mode of disposal is in near-surface impoundments in the vicinity of the respective mine or mill [1]. Such ...
