How to Test If Something is Gold or Copper Our

A gold test kit will tell you if a piece of metal is gold or copper. Score a half-inch line on the flat black test stone provided in the gold test kit by rubbing the edge of the metal up and down against its surface two or three times. This will leave a thin line of metal particles embedded in the stone.

Eliminating Copper from Gold Ore

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 ...

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.

Mineral Deposit Value - How to Calculate the

As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).
