Mineral Beneficiation or ore dressing of run-of-mine ore is an upgrading process to achieve uniform quality, size and maximum tenor ore through the removal of less valuable material. Beneficiation benefits the costs of freight, handling, and extraction (smelting) reduce, and the loss of metal through slag. Usually carried out at the mine site, it saves time and costs and allows selective, profitable bulk mining. This practical guide presents the essentials of mineral dressing and its support operations. It explains the terms and techniques and provides basic formulas, methods and practical...

Across the continental United States, one can identify 20 distinct forest cover types. Most of these are to be found on federal lands managed by the U.S. Forest Service and Bureau of Land Management. Those responsible for the management of trees that form the 20 different cover types and the diversity of forest wildlife that reside in them must have a solid grounding in concepts of forest management, especially silviculture, as well as concepts of wildlife management, in order to integrate both as part of any effective natural resource management plan.

This 30^st jubilee volume (2010) of "Palaeoecology of Africa" looks back and reflects the "state of the art" of what is actually known on former African climates and ecosystems in the format of review articles authored by specialists in the field. New research articles on climate and ecosystem dynamics as well as applied topics on geomorphic hazards and future environmental trends in Africa are included.
This book will be of interest to all concerned with ecosystems dynamics, tropical forests, savannahs, deserts and related development problems of third world...

An ecosystem's complexity develops from the vast numbers of species interacting in ecological communities. The nature of these interactions, in turn, depends on environmental context. How do these components together influence an ecosystem's behavior as a whole? Can ecologists resolve an ecosystem's complexity in order to predict its response to disturbances? Resolving Ecosystem Complexity develops a framework for anticipating the ways environmental context determines the functioning of ecosystems.

Taking a broad and innovative informational approach, Sustainable Agriculture and New Biotechnologies is the first book to apply omic technologies to address issues related to understanding and improving agricultural sustainability in the food production process. The transformation from industrial to sustainable agriculture is discussed within the frameworks of new biotechnologies and global environmental changes. While considering this transformation, the book covers:

• The use of new biotechnologies to help in the creation of more sustainable agricultural...

A Natural History of the Intermountain West was written to inform people about the wild world around us, with the idea that we all crave a connection to the natural world to ground us and give us a sense of place. It is also a book about change. While species are described throughout the chapters, the text is focused more on the profound processes that have shaped western ecosystems, based on a belief that understanding those processes is more meaningful than a list of names. The ways and the rapidity with which enormous ecosystems replace one another and sometimes even return as...

Wild New Jersey invites readers along Wheeler's whirlwind year-long tour of the most ecologically diverse state for its size in America. Along with the expert guidance of charismatic wildlife biologists and local conservationists, he explores...
