The potential of deep seabed polymetallic nodules
Tormová, Lucia ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The deep seabed polymetallic nodules are one the major types of deep-sea ore resources. Oceanic deposits of these raw materials represent a potential source of numerous metals that are in short supply on the land-base deposits at the nearest future. The process of geological survey to the deep ocean floor is considered to be an onset of a quantitatively new stage in the process of mineral resource extraction. Continuation of the on-going work on polymetallic nodule deposits within the Clarion-Clipperton Zone is regarded as a serious task to be undertaken over a period until the year 2025, with a due consideration to advance in designing of an efficient mining unit and application of modern processing technologies for extraction of major metals : manganese, nickel, cobalt and copper. A prerequisite of a rational management of oceanic resources is the preservation of natural oceanic environment. Considered is the extraction's profitability of a concrete deposit within the Clarion-Clipperton Zone, which is the exploration area of the IOM, with annual production scale of 2.2 Mt of wet nodules for the year 2025.
The Oil Sands and Economic, Environmental and Political Aspects of their Utilization
Tormová, Lucia ; Němcová, Ingeborg (advisor) ; Horák, Jiří (referee)
The intention of the work is to find, name and explain key factors, which will most likely influence the future of oil sands. The work offers in direct connection with predicted future global energy consumption and with further factors various views on their utilization possibilities. It focuses on evaluation of obstacles within oil sands sector and provides with adequate solutions. The aim of the work is to estimate appropriate conditions for bitumen as well. The first chapter analyzes the current state of world oil resources and verifies the peak oil theory. The second chapter describes oil sands characteristics and their exploitation. The third one focuses on bitumen price, on oil price, which is required by oil sands industry and on extraction costs. The fourth chapter is trying to solve the environmental issues and the fifth one possible political consequences.
