  • Iron oxide copper gold ore deposits Wikipedia

    Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. 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

  • How to Use Bleach on Gold Ore to Remove Gold Sciencing

    How to Use Bleach on Gold Ore to Remove Gold When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore. This was the first commercial method used for gold extraction. Place the ore into the mortar and grind it to the size of sand grains. Put the ore grains into a stone bowl. Add the 35-percent hydrochloric acid to the sodium hypochlorite bleach

  • How Is Gold Extracted From Gold Ore? Sciencing

    Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold
