Often before roasting, the ore has already been partially purified, e.g. by froth flotation.


  • 4 Ways to Tell if Gold Is Real - wikiHow

    Jan 27, 2008· To tell if gold is real, try dropping it into a glass of water. If it floats, it's probably not real gold, since gold is very dense. You can also try holding a strong magnet, like the kind you can find at hardware stores, up to the metal to see if it sticks to it. If it sticks, it probably isn't real gold, since gold isn't magnetic.
