oxidised copper ore processing

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 the extraction of oxide ores.

Polished sections of the copper ore sample were studied under reflected light optical microscope and different size fractions were investigated using a zoom stereomicroscope. Few polished sections were also studied under scanning electron microscope (SEM) with EDAX to confirm the composition of some mineral phases.

How to Process Copper Ore: Beneficiation Methods

2020-10-27  Secondary copper sulfide ore is easy to oxidize and more difficult to float than original copper ore. As for the grinding and floating process, it is more advantageous to adopt the stage grinding and floating process for refractory copper ore, such as the re-grinding and re-separation of coarse concentrate, re-grinding and re-separation of bulk concentrate, and separate treatment of medium ore.

A review of the beneficiation of copper-cobalt

2019-11-1  For Cu–Co ores in the DRC, oxidised ore deposits have historically been the main source of Cu–Co as they are relatively simple to process, mainly by leaching/solvent extraction/electrowinning. As high-grade oxidised Cu–Co ores become depleted, importance is placed on the mining of low-grade disseminated ores.
