how to identify gold ore from copper ore

  • What Does Gold Ore Look Like? Sciencing

    Some forms of gold ore make recognizing its gold content challenging. For example, pyrite and arsenopyrite are carriers of invisible quantities of submicroscopic gold. Another obstacle to seeing gold in gold ore occurs when gold entwines with other metals within the ore.

    These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging from 0.1 to >3 grams per tonne (parts per million).

    IDENTIFYING GOLD METAL IN THE ROCK Basic

    Many people who may have difficulty to identify the gold in the rock, because gold is usually often confused with the kind of carrier minerals pyrite, chalcopyrite, pyrhotite, pentlandit and gold-colored mica, because the mineral carrier is very similar to a vein of gold ore.

    geology How do geologists find ore deposits? Earth

    So, for example, if you have a lot of gold veins in one area, and lots in another area, then you look at what is needed for these veins to form. Once you have a reasonable idea of possible ways to form your ore, then you have something that you can look for.

    How to Test If Something is Gold or Copper Our Pastimes

    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.

However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to be separated. Copper minerals and

    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
