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 ...

Copper complexes that can be present in cyanide liquors include Cu (CN) 2 −, Cu (CN) 3 2 −, and Cu (CN) 4 3 − with the proportions dependent on the pH, copper concentration, and free cyanide concentration. The main issue facing the process engineer is the fact that minimization of cyanide consumption is favored by the formation of species with a low copper:cyanide mole ratio, e.g., Cu ...

Keweenaw Peninsula Copper Mines - Mining History Association

The ore was next pulverized by steam stamps. Copper was recovered using Woodbury jigs and shaking tables. Fine particles called slimes next went to three-decked Dorr thickeners before tailings were disposed in Torch Lake. Flotation and leaching processes were added to the mills to boost copper recovery as ore grades declined.
