Copper Mining and Extraction: Oxide Ores

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for ...

Heap Leaching Oxide and Sulfide Copper Ores

The acid consumptions curves for the oxide copper ore (number 3) with a high iron oxide-tactile gangue were somewhat different than those of oxide copper-porphery gangue ore number 1. In tests 9 through 14 the incremental acid curves were generally low at the start, fairly high after 3 to 4 days of leaching, and very high thereafter.

The Extraction of Copper - Chemistry LibreTexts

The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper (II) ions in the chalcopyrite are reduced to copper (I) sulfide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron (II) silicate slag which ...

Azurite: The blue gem material, ore of copper, and pigment.

Geologic Occurrence. Azurite is a secondary mineral that usually forms when carbon-dioxide-laden waters descend into the Earth and react with subsurface copper ores. The carbonic acid of these waters dissolves small amounts of copper from the ore. The dissolved copper is transported with the water until it reaches a new geochemical environment.
