  • Photos of gold ores, quartz, telluride gold ore and gold

    This is a piece of gold ore from the famous Witwatersrand gold deposits of South Africa. The ore consists of conglomerate pebbles mostly of quartz, in a sandy matrix, with abundant pyrite in the cement. The gold, which occurs in the cement but not in the pebbles, is closely connected with the pyrite and is not visible to the naked eye.

    gold Physical Characteristics Gold is the most malleable and ductile of metals. It may be beaten into gold leaf as thin as 4 millionths of an inch. An ounce of gold may be drawn into a wire more than 40 miles long. Gold is a good conductor of electricity, though it is inferior to silver and copper in that respect.Gold mixes, or alloys, readily with other metals.
