how to identify gold ore from copper ore

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.
