Rare metals and important elements have been discovered in manganese nodules on various ocean floor systems worldwide. The following elements are present in our nodules: manganese, iron, silicon, aluminum, nickel, copper, cobalt, oxygen, hydrogen, barium, potassium, titanium, sodium, traces of cobalt, and others.
