2020-1-1 · The overall objective of mining is to remove the raw uranium-bearing material from the earth. Milling follows the mining process, which is intended to extract the uranium from the ore. Milling is largely a chemical process, which yields a product much higher in uranium content than mining, but not yet pure enough for the fabrication of nuclear fuel.

Copper Mining and Processing: Processing Copper

The first steps of copper processing are the same for both ores: mining and transporting. Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.
