• Gold Mining and Processing: Everything you Need to Know

    The Basics of Gold Mining and ProcessingWhat Is Gold Used for?Where Is Gold Found?The Gold Mining ProcessIn addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to 2770 metric tons. With continued advancements in mining technology, this growth trend is likely to continue.[photo via]
