Manganese Nodules Polymetallic Ocean Floor Mining

Manganese Nodules
Manganese nodules are the most widespread undersea mineral resource, composed mainly of manganese minerals and are found in lumps of varying sizes. Rare metals and important elements have been found in manganese nodules discovered on various ocean floor systems throughout the world. The following elements have been demonstrated to be present in our nodules: manganese, iron, silicon, aluminum, nickel, copper, cobalt, oxygen, hydrogen, barium, potassium, titanium, sodium, traces of cobalt and others. The estimated age of these nodules is approximately 2.5 million years old.

Our manganese nodules were obtained in a scientific materials trade with a major university. Each ships with a Certificate of Authenticity and group XRF analysis. Last Updated: June 28, 2022
