Minerals: Polymetallic Nodules

Polymetallic Nodule Polymetallic nodules cover vast areas of the ocean floor and are more abundant in areas off the west coast of Mexico in the Pacific, known as Clarion-Clipperton Fracture Zone (CCZ); in the Central Indian Ocean Basin (CIOB); and in the Peru basin. They are composed mainly of Mn, Fe, Silicates and hydroxides. It is the trace metal contents such as Ni, Cu, Co, and Mn and Rare Earth Elements (REE) that are attracting interests to mine these deposits to meet the growing demand for these metals. The nodules vary in size from micro-nodules to about 20 cm, the common size being two to eight centimeters.
