Copper Mining and Extraction: Oxide Ores

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 ...

Generally such oxide copper-cobalt ores are recovered by sulphidisation process. In Congo, the copper mineralisation is mainly composed of malachite, pseudo malachite, and chrysocolla. Cobalt in such oxide copper ores occur as heterogenite. Since the copper minerals are oxide in nature, they do not respond to flotation with xanthate collectors.

Heap Leaching Oxide and Sulfide Copper Ores

Jun 22, 2019  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.

Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.
