Copper Mining and Processing: Processing Copper Ores ...

Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leaching and Solvent Extraction of Oxide Ore.

Copper Ores - Technische Fakultät

Native copper occurs at the surface of ore bodies and sometimes deeper in the ore body. Some of the compounds formed in the oxidation zone are water soluble. Rain leaches this stuff to below the groundwater level, where it precipitates again, thus enriching the ore concentration at this level.

Copper Ore - an overview | ScienceDirect Topics

Beneficiation of copper ores produces concentrates consisting mostly of sulfide minerals, with small amounts of gangue oxides (Al2 O 3, CaO, MgO, and SiO 2 ). Theoretically, this material could be directly reacted to produce metallic Cu by oxidizing the sulfides to elemental copper and ferrous oxide: (5.1) CuFeS 2 + 2.5 O 2 → Cu ° + FeO + 2 SO 2

COPPER Copper production - TU Delft

Separation of special copper ores such as those containing molybdenite or with high zinc or lead content (Canada) is also possible by flotation methods. Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching.

copper processing - Ores | Britannica

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.
