Polymetallic Manganese Nodules 50 lbs
Fifty pounds of manganese nodules are for sale here for scientific study or precious metals recovery. Rare metals and important elements have been found in manganese nodules that have been discovered on various ocean floor systems throughout the world.
Collection site: The Clarion-Clipperton Fracture Zone, northeast equatorial Pacific Ocean floor.
A professional XRF elemental assay metallurgical laboratory printout analysis is included. 50 lbs for sale.
The following elements have been demonstrated to be present: manganese, iron, silicon, aluminum, nickel, copper, cobalt, oxygen, hydrogen, barium, potassium, titanium, sodium and traces of a few others. The estimated age of these nodules is approximately 2.5 million years old.

Estimated 7,500 pieces. Shipped in 1 large white durable canister.
These manganese nodules were obtained in a scientific materials trade with a university, in 1993. They were originally mined from the ocean floor by a scientific research expedition vessel to the Pacific Ocean, in 1979. The inset picture is shown for use as a sampling of specimen sizes.
These polymetallic nodules ship with a Certificate of Authenticity, tag, and information about the nodules.
