Flowsheet Options For Processing Copper Gold & Gold …
2. Copper gold ores-these are ores where copper is predominant and gold occurs as a secondary economic mineral. The key qualifying ore characteristics are: • Are the copper minerals oxides, silicates, sulphides or a mixture? • How soluble are the copper minerals in acid (especially sulphuric acid) and cyanide solubility?
Solvent Extraction & Electrowinning (SX/EW) Plant Design
The mineral resource is a porphyritic sulfide deposit that had a copper oxide capping. Mining commenced under Minero Peru in April 1977 with dump leaching of coarsely crushed oxide ores, principally chrysocolla and bronchantite. Copper was extracted on asphalt-lined leach pads and recovered in the first solvent extraction and electrowinning (SX ...

(PDF) Leaching of Copper Sulphides
In the ten years from 2003 to 2013 global mine production of copper has increased by over 23% to meet demand while the weighted average head grade has dropped from 0.9 to 0.7% Cu.
Understanding Copper Oxides & Sulfides
Understanding Oxides. Copper oxides form when sulfide minerals are exposed to oxygen and water. This weathering process enriches copper content compared to the original sulfide deposit. Oxides are typically found within a few hundred meters of the surface, but can run deeper along fractures and faults that allow oxidizing water to penetrate.

SART for copper control in cyanide heap leaching
Nearly all copper oxide minerals show significant solubility in cyanide (Hedley and Tabachnick, 1958; Marsden and House, 2006). Many sulphide copper minerals also show significant solubility, although less so than the copper oxide minerals. The overall cyanide-soluble copper fraction of a particular ore is best estimated through bottle roll and/or
