با ما تماس بگیریدA World Bank report in 2020 found that the production of minerals like cobalt could increase by nearly 500% by 2050 to meet the growing demand for clean energy technologies.
The present paper revises this by showing that the choice between mining crust and nodules depends on fluctuations in the price of nickel. A Monte Carlo simulation proves that cobalt crust mining could be reasonably preferred to manganese nodules at cobalt prices of $40–60/kg if the price of nickel fell below $11/kg.
The metals in those nodules can be used to build electric vehicle (EV) batteries, cell phones, solar panels and other electronic devices. They are separate from rare earths, a group of 17 metals ...

In contrast to the prevailing perception of non-viability of nodule mining, our analysis indicates a fair degree of economic feasibility and commercial sustainability to mine the deep …
Currently, there is no large-scale mining of marine mineral resources anywhere in the world. However, a number of countries and companies are actively pushing forward with studies of resource potential, economic and environmental requirements for resource development, and pilot projects to evaluate deep-sea mining technologies.
Polymetallic nodule mining at abyssal depths in the Clarion Clipperton Fracture Zone (Eastern Central Pacific) will impact one of the most remote and least known environments on Earth. Since vast ...
The Cook Islands (CI) is a self-governing small island developing state in the South Pacific region. It comprises 15 separate islands or island groups spread over an Exclusive Economic Zone (EEZ) of around 2 million km 2 (Fig. 1) Cook Islands EEZ is situated between latitudes 6° and 25° South and Longitudes 155° and 168° West.The islands of CI form two …
The deep-sea is rich in mineral resources, and deep-sea polymetallic nodules are considered to be the most likely resource for commercial exploitation. Since the discovery of polymetallic nodules by mankind, researchers around the world have made long and arduous explorations in the exploitation of deep-sea polymetallic nodules and have proposed various …
Mine planning of land-based mineral deposits follows well-established methods. The deep sea is currently under exploration, but mine planning approaches are still lacking. A spatial planning tool to assess the techno-economic requirements and implications of manganese nodule mining on deep-sea deposits is proposed in this paper. The …

Worldwide production of nickel, copper, and cobalt from conventional land-based mines also increased considerably between 1965 and 1990 despite the deterioration in investment conditions in developing countries—not all mining took place there—and despite sluggish economic growth in the consumer states (Fig. 1).Consequently, in the early 1980s, …
Polymetallic nodule fields provide hard substrate for sessile organisms on the abyssal seafloor between 3000 and 6000 m water depth. Deep-seabed mining targets these mineral-rich nodules and will ...
International seabed authority (ISA), authority of OSN developed study, from which results, that mining is possible, but under the strict rules. The seabed hidden in depth about four to six …
Polymetallic nodules vary in diameter from less than one to tens of centimetres and acquire economically interesting quantities of critical metals (metals that are essential to …
One mining operation as described in this paper would produce 37.050 × 10 3 t of nickel, 32.400 × 10 3 t of copper and 6.375 × 10 3 t of cobalt annually, representing approximately 2.32 per cent, 0.20 per cent and 7.50 per cent of their respective markets. Because manganese is the most abundant constituent metal in the polymetallic nodules, it is important to understand …
The other found metal production from nodules "may produce less waste of lower severities" compared to land-based mining. "Nodule exploitation would damage abyssal habitats and may impact ...
Many scientific, technical, and economic publications are available on ferromanganese nodules (FNs) because FNs have been considered to be the primary commercial mining target in deep-sea mineral resources for the past more than 50 years [1,2].Geological distribution features were studied by many scientists [3,4,5,6,7].On the basis …
Prospectors consider a mining site economically viable if the nodule concentration exceeds about 10 kilograms per square meter, the nodules are covered by little or no sediment so they are easy to ...
