Available in PDF, EPUB and Kindle. Book excerpt: The effects of several variables affecting the economic performance of proposed manganese nodule mining ventures were evaluated using an improved version of the Texas A&M University's Ocean Mining Payout Analysis Program. After tax Internal Rate of Return (discounted cash flow) was used as the primary criterion of performance along with total funding requirements. Variables studied included ore production rate (throughput), processing plant location, construction period, depletion, corporate structure type, processing plant type and financing. Metal pricing used in the analysis was "normal" 1970's pricing which (with the exception of cobalt) is higher than current metal prices. Overall results show that favorable combinations of the variables can produce after tax rates of return as high as 30 to 35 percent.

Available in PDF, EPUB and Kindle. Book excerpt: Manganese nodules lying on the ocean floor beyond national jurisdiction and containing such strategic minerals as cobalt, copper, manganese and nickel are currently considered to constitute the highest-valued deep ocean mineral resource and regarded by many as the "common heritage of mankind". Not surprisingly, the exploitation of minerals from the sea bed was one of the most controversial issues discussed at the Third United Nations Conference on the Law of the Sea from 1973 to 1982, which led to the adoption of a new Convention on the Law of the Sea in Jamaica in December of 1982. However, the still ongoing international debate on the Convention I s regime to govern deep-sea mining reveals that the central economic problems involved are far from being defi nitely settled. In view of the importance of this issue, the Kiel Institute of World Economics launched in 1980 a major research project on allocational and distributional aspects of the use of ocean resources. A comprehensive analysis and evaluation of the new Law of the Sea Convention has al ready been published (see Wilfried Prewo et al., Die Neuordnung der Meere - Eine okonomische Kritik des neuen Seerechts. Kieler Studien No. 173. Tlibingen: J.C.B. Mohr, 1982).
Download or read book An Economic Analysis of a Pioneer Deep Ocean Mining Venture written by John E. Flipse and published by . This book was released on 1982 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 3 million ton per year, three metal, vertically integrated, ocean exploration, mining, transportation and ore-processing and metal-marketing system is defined and the capital and operating costs estimated in 1980 U.S . dollars . A basic return-on-investment 11pay-out11 analysis model is presented with several alternate cases investigated. A series of tests is performed to determine the system's sensitivity to realistic variations of key costs and schedule. For a gross investment of almost $1.5 billion, or a fixed capital investment of about $1 billion, an ocean mining system producing nickel, copper and cobalt will yield approximately $415 million in annual revenues, a before-tax profit of about $180 million and an after-tax profit of less than $100 million, providing an unsatisfactory low internal rate of return of approximately seven percent. It is unlikely that ocean mining will be undertaken using the system defined herein at this level of return unless a critical feedstock for a company's major product is produced or a national need for a strategic metal develops . This conclusion is entirely consistent with today's low level of commitment to long-term, capital-intensive natural resource development projects.

Available in PDF, EPUB and Kindle. Book excerpt: This volume discusses environmental issues associated with deep-sea mining, with an emphasis on potential impacts, their consequences and the policy perspectives. The book describes the methods and technologies to assess, monitor and mitigate mining impacts on marine environments, and also suggests various approaches for environmental management when conducting deep-sea mining. The volume brings together information and data for researchers, contractors, mining companies, regulators, and NGOs working in the field of deep-sea mining. Section 1 highlights the various environmental issues and discusses methods and approaches that can help in developing environmentally sustainable deep-sea mining. Section 2 details the results and outcomes of studies related to impact assessment of deep-sea mining, and proposes methods for monitoring. Section 3 discusses the need and means for developing data standards and their application to deep-sea mining. Section 4 discusses the policies, approaches, and practices related to deep-sea mining, suggests formats for developing environmental impact statements (EIS) and environmental management plans (EMP), and describes national and international regulations for environmental management. Section 5 concludes the text by putting deep-sea economic activities into an environmental context and conducting techno-economic analyses of deep-sea mining and processing.

This book was released on 2019-11-01 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The book looks at the need of minerals for humanity, how and what the oceans offer as minerals in general, the technological developments achieved and the insight into future technologies and designs in this field before finally focusing on the mineral wealth of the Indian Ocean. It eventually poses some tough questions that need answers if deep seabed mining is to become a success in the future. In addition, it discusses the efforts of the key players in this field operating in the Indian ocean that has rejuvenated the deep seabed mining both economically and strategically. Since, commercial profitability of marine minerals occurs only if the demand is greater than the supply, at times, the decision gets governed by strategic reasoning. Hence, the book aims to give an idea of the driving forces that guide such decision-making and the development of deep seabed mining.

Download or read book Perspectives on Deep Sea Mining written by Rahul Sharma and published by Springer Nature. This book was released on 2022-01-13 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a sequel to ’Deep-Sea Mining: Resource Potential, Technical and Environmental Considerations’ (2017) and ‘Environmental Issues of Deep-Sea Mining: Impacts, Consequences and Policy Perspectives’ (2019), and aims to provide a comprehensive volume on different perspectives of deep-sea mining from specialists around the world. The work is timely, as deep-sea minerals continue to enthuse researchers involved in activities such as ascertaining their potential as alternative sources for critical metals for green energy and other industrial applications, as well as technology development for their sustainable exploration and exploitation, while addressing environmental concerns. With a steady increase in the number of contractors having exclusive rights over large tracts of seafloor in the ‘Area’, i.e. area beyond national jurisdictions, the International Seabed Authority, mandated with the responsibility of regulating such activities, is in the process of developing a code for exploitation of deep-sea minerals. These, coupled with growing interest among private entrepreneurs, investment companies and policy makers, underscore the need for updated information to be made available in one place on the subject of deep-sea mining. The book evaluates the potential and sustainability of mining for deep-sea minerals compared to other land-based deposits, the technologies needed for mining and processing of ores, the approach towards environmental monitoring and management, as well as the regulatory frameworks and legal challenges to manage deep-sea mining activities. The book is expected to serve as an important reference for all stakeholders including researchers, contractors, mining companies, regulators and NGOs involved in deep-sea mining.
