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.

This reduces all of the manganese ore to manganese oxide, which is a leachable form. The ore then travels through a grinding circuit to reduce the particle size of the ore to between 150–250 μm, this increases the surface area to aid in the leaching process. The ore is then added to a leach tank, which contains sulfuric acid and ferrous iron.
