Typically, you would use a flotation process to concentrate the copper and gold. Concentrate would be shipped to smelter for recovery of metals.
Gold is formed independently from rocks so unlike iron or copper there is no 'ore' to extract it from. In general gold is acquired by finding nuggets in rocks. The gold is simply chipped off from the rock. It is extremly difficult if not impossible to extract the small traces of gold that can be found in many rocks and as far as i am aware no commercial technique for acccquiring such gold.
By reduction-oxidation reaction you can extract metals, including Gold, from ore.
At one time, mercury WAS used to extract gold from gold ore. The rock was crushed, and washed over a copper sheet coated with mercury. Gold forms an amalgam with mercury, and some of the gold would be trapped in the mercury. The mercury would be scraped from the copper, and distilled, leaving behind the gold. Other processes are used today.
Through bioleaching, thermal decomposition, displacement, phytomining & electrolysis.
At time mercury was used to extract metallic gold from gold ore. The ore was crushed to powder, and washed over a copper sheet covered in mercury. The gold would combine with the mercury, and be recovered by distilling the mercury. This was very dangerous due to the poisonous nature of mercury- and it only captured about 15% of the gold. It is no longer used in gold mining.
Copper Ore.

After the initial smelting to extract copper from the ore it still has to go through electroplating purification.

The method used to extract Cu from its ore depends on the nature of the ore.

Ore, as in rocks which contain sufficient metal to extract and it is economical to do so. Ores include bauxite, a copper ore. Ores can be used to extract precious metals which in turn can be used for electrical wiring, in the case of copper or as a catalyst, in the case of Haematite, Iron ore (the haber process).
many, but not all, copper ore deposits also contain gold
Highly toxic cyanide is used to extract gold ore.
yes, it is quite easy to remove cu from its ore because cu is less reactive so less energy is required i.e.it can be removed from its ore by just heating its ore in air for two to three times.
yes because it can only be made by heating copper ore and carbon. The ore breaks down into copper oxide and the carbon then removes oxygen leaving the copper.. copper oxide + carbon = (arrow/ gives out) copper + carbon dioxide hpe it helped :)
No; iron ore is mixed with copper and smelted; the ore needs to be refined to extract pure iron. You cannot make a tool out of ore, but rather with pure iron.
