The alkaline igneous rocks and carbonatites are compositionally and mineralogically the most diverse of all igneous rocks and, apart from their scientific interest, are of major, and growing, economic importance. They are important repositories of certain metals and commodities, indeed the only significant sources of some of them, and include Nb, the rare earths, Cu, V, diamond, phosphate, vermiculite, bauxite, raw materials for the manufacture of ceramics, and potentially Th and U. The economic potential of these rocks is now widely appreciated, particularly since the commencement of the mining of the Palabora carbonatite for copper and a host of valuable by-products. Similarly, the crucial...
Polar law describes the normative frameworks that govern the relationships between humans, States, Peoples, institutions, land and resources in the Arctic and the Antarctic. These two regions are superficially similar in terms of natural environmental conditions but the overarching frameworks that apply are fundamentally different. The Routledge Handbook of Polar Law explores the legal orders in the Arctic and Antarctic in a comparative perspective, identifying similarities as well as differences. It points to a distinct discipline of "Polar law" as the body of rules governing actors, spaces and institutions at the Poles. Four main features define the collection: the Arctic-Antarctic interfa...
This book focuses on the engineering aspects of phosphorus (P) recovery and recycling, presenting recent research advances and applications of technologies in this important and challenging area of engineering. It highlights full-scale applications to illustrate the performance and effectiveness of the new technologies. As an essential element for all living organisms, P cannot be replaced by any other element in biochemical processes, humans ultimately rely its availability. Today, P is mostly obtained from mined rock phosphate (Pi). However, natural reserves of high-grade rock Pi are limited and dwindling on a global scale. As such, there have been increased efforts to recycle P from secon...
This report presents the world nitrogen, phosphate and potassium fertilizer medium-term supply and demand projections for the period 2014-2018. The FAO/Fertilizer Organizations Working Group met in Nairobi, Kenya, in June 2014 to review the prospects for fertilizer demand and supply, and prepared the forecasts. The African Fertilizer and Agribusiness Partnership (AFAP) and the Fertilizer Association of Southern Africa (FERTASA) provided special regional contributions and presentations.

The book presents the history of Estonia in easily readable form and with compassion for the people whose lives were affected by the events that occurred in the Baltic region. The prolonged occupation of the Baltic region by different European nations not only caused great hardships for the Estonian people, but it also integrated them into the western European cultural community. In that sense, the history of Estonia has had a happy ending. After seven centuries of domination by foreign powers, the people of Estonia are now free, they are well educated, they are creative, they are hard-working, and they are patriotic. The Republic of Estonia has earned the respect and admiration of the people of the world and deserves to be recognized as a modern and successful nation.
Ion-exchange Technology I: Theory and Materials describes the theoretical principles of ion-exchange processes. More specifically, this volume focuses on the synthesis, characterization, and modelling of ion-exchange materials and their associated kinetics and equilibria. This title is a highly valuable source not only to postgraduate students and researchers but also to industrial R&D specialists in chemistry, chemical, and biochemical technology as well as to engineers and industrialists.
