Besides, the nodules are rich in other minerals like iron, copper, cobalt and nickel that find applications in other fields (Hein et al., 2013). Overall, the mining of manganese nodules creates employment opportunities and are …
Another argument The Metals Company and others like it make is that the mining – or as they prefer to term it, collection – of these nodules can be done in a less invasive and more energy efficient way than traditional mining operations. "Polymetallic nodules lie around like golf balls on a driving range," Barron explains.

However, there are several considerations for the sustainable development of deep-sea mining.A typical area of 75,000 km ² with an estimated nodule resource of >200 million tonnes is expected to ...
3 Technical Economic Study of the Sea-Bed Mining Currently, there are number of proposals of technical solutions for sea-bed mining of polymetallic nodules. It will be necessary to define the structure of such a system for planning of mining, that is, the number of mining collectors, buffers, and vertical transport devices and vessels.
Although deep-sea manganese nodules were discovered over a'century ago by scientists of the HMS Challenger expedition, few analyses of the nodules for the economically significant elements such as nickel, copper, cobalt and molybdenum were made in those early days and no consideration was given to these deposits as a possible commercial source of metals until the …
The nodules are said to contain 610,000 tonnes of cobalt (75 years of Japan's consumption) and 740,000 tonnes of nickel (11 years).
Polymetallic nodules are lumps of iron, manganese hydroxides, and rock partially submerged in many parts of the ocean floor. If their concentration exceeds 10 kg per sq. m, mining them is considered to be economically feasible — and many countries are planning to do so as a new resource. Way forward
Deep-sea polymetallic nodules are a mineral resource with potential for commercial development. Due to the unique deep-sea environment in which they are found, specialized technology and equipment are required …

The ISA, primarily targeting mining contractors, has granted exploratory licences for polymetallic nodules to 19 firms. These nodules, which have an appearance similar to little rocky objects, contain significant amounts of metals such as cobalt and nickel. These metals are essential components for the rapidly growing lithium battery industry.

The deep sea mining may distract the keystone and the foundation species. Way Forward: India needs to partner with private sector and build conducive policy and legal framework to make the programme a success. Proper survey and exploration, environmental studies, technology development in mining and extractive metallurgy are needed.
