Uranium mining - Wikipedia

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2015 amounted to 60,496 tonnes. Kazakhstan, Canada, and Australia are the top three producers and together account for 70% of world uranium production. Other important uranium producing countries in excess of 1,000 tons per year are Niger, Russia, Namibia, Uzbekistan, China, …

Nuclear fuel cycle - Wikipedia

Mined uranium ores normally are processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching. The milling process commonly yields dry powder-form material consisting of natural uranium, "yellowcake", which is sold on the uranium market as U 3 O 8. Note that the material ...

Uranium - Industrial-Craft-Wiki

Uranium is a metal resource added by IC² and generated as ore between layers 0 and 64, usually in groups of up to 2 blocks. It requires an iron pickaxe or better to mine. Several forms of uranium are radioactive and will poison (often quite severely) anyone handling them without the use of a Hazmat Suit.. Forms. These forms of uranium are seen during ore processing:
