Discriminating Uranium and Copper mills using satellite imagery
The froth from the flotation process contains the bulk of the Copper. The froth is dried and then sent directly to a smelter. The smelter may be located at the mill site or may be located elsewhere. The smelter converts the Copper concentrate into blister Copper which is further refined to produce anodic Copper.

The nuclear fuel cycle
Despite the name, the concentrated uranium product is typically a black or brown substance called yellowcake (U 3 O 8).Mined uranium ore typically yields one to four pounds of U 3 O 8 per ton of ore, or 0.05% to 0.20% yellowcake. The solid waste material from pit and underground mining operations is called mill tailings.The processed water …

Copper Production: How Is Copper Made?
The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

How is uranium made into nuclear fuel?
The vast majority of nuclear power reactors use the isotope uranium-235 as fuel; however, it only makes up 0.7% of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium-235 concentration from 0.7% to between 3% and 5%, which is the level used in most reactors.

Uranium ore
Uranium ore is a resource found on the map. Instead of being smelted in a furnace, uranium ore must be processed in a centrifuge to produce uranium-235 and uranium-238, which is used to craft fuel for the nuclear reactor and in various types of ammunition.. Uranium ore is different from the other ores, as it requires sulfuric acid to be fed into the …

Low grade ores – Smelt, leach or concentrate?
Bacterially-assisted heap leaching of low-grade copper sulphides is a developing technology that has been applied successfully to the extraction of copper from sulphide minerals such as chalcocite at ore grades down to 0.15% ( Watling, 2006 ). The ore is typically crushed to about 6–13 mm prior to stacking into heaps.
