Mining: Making the Most of Radioactive Caches

If experts deal with dry ore, they'll most likely stick with a type of open-pit or underground mining. Open-pit removal for uranium closely resembles what's done to mine other metal ore. Experts and miners will use machines and explosives to create a pit. Get price

Known Facts and Hidden Dangers of Uranium Mining,

She got some uranium ore from the Erz mountains, not very far from here. She chemically separated the uranium from the rest of the crushed rock (she had to crush the rock and dissolve it in acid to get the uranium out, which is what we still do today in mining uranium) and she found that even after the uranium had been removed, the crushed rock remained very radioactive -- much more so than Get price

NRC: Uranium Recovery (Extraction) Methods

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 Get price

How is Uranium Produced?

Underground mining is necessary where the uranium ore is too far underground to be reached by open-pit mining. The uranium ore is blasted and the resulting debris transported to the surface. After both open-pit and underground mining, the uranium ore concentrated in the extracted rocks is weak, usually only around 0.3%. Get price

Mining

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on Get price

what can you actually do with uranium ore?

2010/11/24Underground uranium mining is in principle no different to any other hard rock mining and other ores are often mined in association (e.g. copper, gold, silver). Once the ore body has been identified a shaft is sunk in the vicinity of the ore veins, and crosscuts are driven horizontally to the veins at various levels, usually every 100 to 150 metres.

Uranium mining

It is sometimes referred to as 'yellowcake' and generally contains more than 80% uranium, while the original ore may contain as little as 0.1% uranium. In a mill, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium. Get price
