Uranium can be obtained by mining Uranium Ore. Uranium ore has a kind of light greenish colour and requires an iron pickaxe or higher to mine.
Compressing[]
It can be compressed in a Compressor to obtain Refined Uranium.
In the previous version of Technic Uranium was incredibly valuble in EE, worth 6 diamonds when converted (EMC value?) However, in the current version it has been reduced to only 1/2 of a diamond (EMC value?)
