Manganese Nodule Mining and Economic Rent Nina W. Cornell Recommended Citation ... The actual number of potential mining sites is unknown except perhaps to the companies considering the industry. It seems likely, however, that the total number of commercially viable sites are limited and that some of them are more valuable than others

    Manganese nodules are found along the ocean floor and are mined for their Manganese, but not as much as their terrestrial sources. Experts believe that deep seabed mining could become a source of Manganese ore and could significantly shift from land to ocean, but with potentially severe environmental implications

    Abstract Because of ever-growing demand for strategic metals, the focus of the international community has fallen on deep sea manganese nodules occurring at a water depth of more than 4500 m. We present an economic appraisal and strategy for mining of nodules from the Indian Ocean Nodule Field- one of the four economically potential areas in the world oceans

    Manganese (Polymetallic) Nodules of the Abyss. Manganese nodules form on vast deep-water abyssal plains and comprise primarily of manganese and iron, though significant amounts of other metals are also found in these structures (Figures 2A,B).Nodules are potato-like in shape, 4–10 cm in diameter, and are thought to form in a process that takes millions of years in which

    This is still the area considered of greatest economic potential in the global ocean because of high nickel (Ni), copper (Cu), and Mn contents and the dense distribution of nodules in the area. While the mining of nodules was fully expected to begin in the late 1970s or early 1980s, this never occurred due to a downturn in the price of metals on the global market
