Ilmu Ilmu Bumi Geologi. That said, I've been able to recover nice Mn nodules from MnO2 thermites. The idea that the ocean floor might host a rich variety of valuable minerals was first considered in 1873, when the HMS Challenger recovered a number of manganese nodules from the bottom of the Pacific, Indian and Atlantic Oceans. These have been dated as 24,000 to 30,000 years old. Metal contents, concentrations, depths, and metal ratios of manganese nodules containing: 14. Creative Commons image by Walter Kölle. The highest concentrations of manganese nodules have been found on vast abyssal plains in the deep ocean between 4,000 and 6,000 meters (13,000 and 20,000 ft). Most of the area consists of a rather A bed of manganese nodules from deep offshore of the Cook Islands; photo sourced from Hein et al., 2015, taken during a Japanese research cruise in the year 2000. The equipment for diamond production, however, is deployed in only 150 metres of water near the coast. Nodules range from about 2 to 10 centimeters across.See a photo of more manganese nodules. The seafloor is thought to hold trillions of dollars’ worth of metals, and this Pacific island nation is making bold moves to get a jump on the global competition to plumb these depths. A bed of manganese nodules from deep offshore of the Cook Islands; photo sourced from Hein et al., 2015, taken during a Japanese research cruise in the year 2000. Manganese nodules are usually located at depths below 4000m and are composed primarily of manganese and iron and elements of economic interest, including cobalt, copper, and nickel and make up a total of around 3% by weight (Margolis and Burns, 1976). Manganese is a silver metallic element with an atomic number of Manganese Nodules: Nuggets of Valuable Minerals Sitting on the Abyssal Plain The Indian government, which has spent about US$40 million surveying the site, estimates that reserves of the nodules — which are rich in manganese, copper, nickel, cobalt and iron — could be worth as much as US$200 billion.

Manganese nodules were discovered in 1868 in the Kara Sea, in the Arctic Ocean off Siberia. Meanwhile, the value of nodules — containing manganese, nickel, copper and cobalt — also reaches into the trillions. The problem recovering metal from manganese thermites is not that they are 'explosive', but that the boiling point of manganese is very close to the temperature the thermite runs at. Kennecott Copper had explored the potential profits in manganese nodule mining and found that it was not worth the cost. On top of the environmental issues and the fact that the profits had to be shared, there was no cheap way to get the manganese nodules off the sea floor.
