Jul 09, 2012 0183 32 Extracting gold from copper 2006 Q My name is Tommy I just got a job at a train yard, we move a lot of copper concentrate through our yard which inevitably spills here and there Someone at work told me that the concentrate a granular substance is copper that has just been taken from the mine and has yet to be refined...

When it is economically feasible, a mine may extract both types of copper minerals when it is not possible, mines will only process either the copper oxides or the copper sulfid The first steps of copper processing are the same for both ores mining and transporting Copper mining is usually performed using open-pit mining, in which a ....

Further, through the use of biooxidation, it is now possible to leach many of the copper sulfide minerals present in the ore While chalcopyrite remains refractory to ambient temperature bioleaching, other copper sulfide minerals - the secondary sulfide minerals - such as chalcocite, covellite, bornite, etc - are leachable by today s technology...

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper ....

used to extract gold from low-grade ore deposits crushed ore is placed on pads that have bottoms of asphalt or impervious plastic sheets, a solution of dilute cyanide is sprayed on the ore, the cyanide percolates down through the ore for several weeks to months and leeches out the gold, now a solution, the gold drains off the pad, the gold is pumped to a recovery plant where the gold is ....

Gold extraction refers to the processes required to extract gold from its orThis may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ....

Extracting gold from a printed circuit board is definitely possible but the amount of the gold in the PCB has to be evaluated first The process involves a number of steps which have to be carried out carefully in order to get the desired results There are some instruments and acids involved in the process Necessary precautions must be taken before starting the procedure...

Among the more promising leach systems, copper-promoted, thiosulfate-leaching technology is emerging as an alternative to cyanidation for gold extraction for certain applications The alternative lixiviants are discussed in detail in Chapter 27 however, the implications of application to copper gold ores warrant some consideration here...

But the reason that you can extract the mercury from the mercury oxides exactly is the higher reactivity of the lead higher the reactivity means more difficult to extract the metals from the ore ....

Removing the gold-bearing rock from the ground is just the first step To isolate pure gold, mining companies use a complex extraction process The first step in this process is breaking down large chunks of rock into smaller piec At a mill, large machines known as crushers reduce the ore to ....

Extracting copper from other or Copper can be extracted from non-sulphide ores by a different process involving three separate stages Reaction of the ore over quite a long time and on a huge scale with a dilute acid such as dilute sulphuric acid to produce a very dilute copper II sulphate solution...
