  • Hidden gold in manganese The Treasures Of Utah

    Oct 29 2008· Manganese has the ability of disolving gold when in contact with ground mineral waters. The gold is locked up in the manganese and when the spring water enriched manganese comes in contact with iron any gold it's carrying will precipitate out into the iron (leach out). I have observed this in many different deposits and believe it to be true.
