CN104294057A - Method for extracting gold from copper ...

The invention discloses a method for extracting gold from copper-oxide oxidized gold ores. The method comprises the following steps: 1, carrying out ammonia-cyanide leaching on the copper-oxide oxidized gold ores to obtain an ore pulp; 2, adding hypochlorite into the ore pulp, and stirring to remove copper in order to obtain a copper removed ore pulp; 3, carrying out countercurrent washing on ...

sulphide/oxide copper-gold vein deposit. Until June 2009, the sulphide and oxide minerals were respectively recovered by the well established xanthate flotation of sulphides and acid leaching of soluble oxide copper. The mixed (transitional) sulphide/oxide ores were stockpiled in the absence of an economic processing route due to their poor ...

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 ...

Porphyry copper deposit - Wikipedia

Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic ...

Many diverse ore systems are classified together as iron oxide copper-gold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of ore-forming fluid, metals, or other ore components. Such deposits have (1) Cu, with or without Au, as economic metals; (2) hydrothermal ore styles and ...

Iron oxide ores usually follow a processing path where the copper is leached from the surrounding rock. The ore is first heaped into piles in special leaching areas, and a sulphuric acid solution is sprayed over the heap to gradually dissolve the copper, separating it from the surrounding gangue.

A Poor Man's Method of Smelting Gold | Sciencing

You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
