This new edition has been extensively revised and updated since the 3rd edition published in 1994. It contains an even greater depth of industrial information, focussing on how copper metal is extracted from ore and scrap, and how this extraction could be made more efficient. Modern high intensity smelting processes are presented in detail, specifically flash, Contop, Isasmelt, Noranda, Teniente and direct-to-blister smelting. Considerable attention is paid to the control of SO2 emissions and manufacture of H2SO4. Recent developments in electrorefining, particularly stainless steel cathode technology are examined. Leaching, solvent extraction and electrowinning are evaluated together with their impact upon optimizing mineral resource utilization. The book demonstrates how recycling of copper and copper alloy scrap is an important source of copper and copper alloys. Copper quality control is also discussed and the book incorporates an important section on extraction economics. Each chapter is followed by a summary of concepts previously described and offers suggested further reading and references.

Since overall circuit performance has depended primarily on transistor properties, previous efforts to enhance circuit and system speed were focused on transistors as well. During the last decade, however, the parasitic resistance, capacitance, and inductance associated with interconnections began to influence circuit performance and will be the primary factors in the evolution of nanoscale ULSI technology. Because metallic conductivity and resistance to electromigration of bulk copper (Cu) are better than aluminum, use of copper and low-k materials is now prevalent in the international microelectronics industry. As the feature size of the Cu-lines forming interconnects is scaled, resistivity of the lines increases. At the same time electromigration and stress-induced voids due to increased current density become significant reliability issues. Although copper/low-k technology has become fairly mature, there is no single book available on the promise and challenges of these next-generation technologies. In this book, a leader in the field describes advanced laser systems with lower radiation wavelengths, photolithography materials, and mathematical modeling approaches to address the challenges of Cu-interconnect technology.

Copper in Drinking Water

The safety of the nation's drinking water must be maintained to ensure the health of the public. The U.S. Environmental Protection Agency (EPA) is responsible for regulating the levels of substances in the drinking water supply. Copper can leach into drinking water from the pipes in the distribution system, and the allowable levels are regulated by the EPA. The regulation of copper, however, is complicated by the fact that it is both necessary to the normal functioning of the body and toxic to the body at too high a level. The National Research Council was requested to form a committee to review the scientific validity of the EPA's maximum contaminant level goal for copper in drinking water. Copper in Drinking Water outlines the findings of the committee's review. The book provides a review of the toxicity of copper as well as a discussion of the essential nature of this metal. The risks posed by both short-term and long-term exposure to copper are characterized, and the implications for public health are discussed. This book is a valuable reference for individuals involved in the regulation of water supplies and individuals interested in issues surrounding this metal.

Abnormal metabolism and distribution of both copper and zinc occurs in many inflammatory and degenerative diseases. The pattern of these changes varies at different stages of these diseases and with differing types of conditions. The corollary to this situation is the possibility of using drugs or metal complexes to modify both the perturbed status of copper and zinc and thus the disease states. This book comprehensively reviews the clinical and experimental data on the changes in copper and zinc status in different diseases and the use of various complexes of these metals or drugs to treat a diversity of inflammatory and degenerative conditions.

This is the first book devoted to Montana's long history of industrial newspaper ownership and the consequences for democracy. The work also reveals the costs paid by owners and their journalists, whose credibility eroded as their increasingly constricted newspapers lapsed into ambivalence and indifference. The story offers a timeless study of the conflict between commerce and the notion of a free and independent press.

A wide range of researchers are currently investigating different properties and applications for copper-containing proteins. Biochemists researching metal metabolism in organisms ranging from bacteria to plants to animals are working in a completely different area of discovery than scientists studying the transportation and regulation of minerals and small molecule nutrients. They are both working with copper-containing proteins, but in very different ways and with differing anticipated outcomes.

In Canada's far north, on the western coast of Victoria Island, the Copper Inuit people of Holman (the Ulukhaktokmiut) have experienced a rate of social and economic change rarely matched in human history. Owing to their isolated, inaccessible location, three hundred miles north of the Arctic Circle, they were one of the last Inuit groups to be contacted by Western explorers, missionaries, and fur traders. Since contact, however, they have been transformed from a nomadic and independent, hunting-based society to one dependent upon southern material goods such as televisions, radios, snowmobiles, ATVs, and permanent residential housing provided by the Government of the Northwest Territories. Anthropologist Richard G. Condon witnessed many of these social, economic, and material changes during his eighteen years of research in the Holman community. With translator/research associate Julia Ogina and the elders of Holman, Condon vividly chronicles the history of the Holman region by combining observations of community change with extensive archival research and oral history interviews with community elders. This chronicle begins with a discussion of the prehistory of the Holman region, moves to the early and late contact periods, and concludes with a description of modern community life. The dramatic transformation of the Northern Copper Inuit is also reflected through nearly one hundred photographs and drawings that complement the text. Each chapter opens with a reproduction of one of the striking Holman prints, depicting scenes from traditional Copper Inuit life.
