Copper

From Kazu Kibuishi, creator of AMULET, comes an irresistibly charming pair of characters! Copper is curious, Fred is fearful. And together boy and dog are off on a series of adventures through marvelous worlds, powered by Copper's limitless enthusiasm and imagination. Each Copper and Fred story in this graphic novel collection is a complete vignette, filled with richly detailed settings and told with a wry sense of humor. These two enormously likable characters build ships and planes to travel to surprising destinations and have a knack for getting into all sorts of odd situations.

Explores the history of the useful metal copper and explains its chemistry, its uses, and its importance in our lives.

This work examines the archaeological record of copper mining in the Lake Superior area.

“The convertors would spew it out,” employee Arturo Hernandez recalled, referring to molten metal. “You’d see the ground, the dirt, catch on fire. . . . If you slip, you’d be like a little pat of butter, melting away.” Hernandez was describing work at ASARCO El Paso, a smelter and onetime economic powerhouse situated in the city’s heart just a few yards north of the Mexican border. For more than a century the smelter produced vast quantities of copper—along with millions of tons of toxins. During six of those years, the smelter also burned highly toxic industrial waste under the guise of processing copper, with dire consequences for worker and community health. Copper Stain is a history of environmental injustice, corporate malfeasance, political treachery, and a community fighting for its life. The book gives voice to nearly one hundred Mexican Americans directly affected by these events. Their frank and often heartrending stories, published here for the first time, evoke the grim reality of laboring under giant machines and lava-spewing furnaces while turning mountains of rock into copper ingots, all in service to an employer largely indifferent to workers’ welfare. With horror and humor, anger, courage, and sorrow, the authors and their interviewees reveal how ASARCO subjected its employees and an unsuspecting public to pollution, diseases, and early death—with little in the way of compensation. Elaine Hampton and Cynthia C. Ontiveros weave this eloquent testimony into a cautionary tale of toxic exposure, community activism, and a corporate employer’s dubious relationship with ethics—set against the political tug-of-war between industry’s demands and government’s obligation to protect the health of its people and the environment.

S. A. Chakraborty continues the sweeping adventure begun in The City of Brass—"the best adult fantasy I’ve read since The Name of the Wind" (#1 New York Times bestselling author Sabaa Tahir)—conjuring a world where djinn summon flames with the snap of a finger and waters run deep with old magic; where blood can be dangerous as any spell, and a clever con artist from Cairo will alter the fate of a kingdom. Nahri’s life changed forever the moment she accidentally summoned Dara, a formidable, mysterious djinn, during one of her schemes. Whisked from her home in Cairo, she was thrust into the dazzling royal court of Daevabad—and quickly discovered she would need all her grifter instincts to survive there. Now, with Daevabad entrenched in the dark aftermath of a devastating battle, Nahri must forge a new path for herself. But even as she embraces her heritage and the power it holds, she knows she’s been trapped in a gilded cage, watched by a king who rules from the throne that once belonged to her family—and one misstep will doom her tribe.. Meanwhile, Ali has been exiled for daring to defy his father. Hunted by assassins, adrift on the unforgiving copper sands of his ancestral land, he is forced to rely on the frightening abilities the marid—the unpredictable water spirits—have gifted him. But in doing so, he threatens to unearth a terrible secret his family has long kept buried. And as a new century approaches and the djinn gather within Daevabad's towering brass walls for celebrations, a threat brews unseen in the desolate north. It’s a force that would bring a storm of fire straight to the city’s gates . . . and one that seeks the aid of a warrior trapped between worlds, torn between a violent duty he can never escape and a peace he fears he will never deserve.

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.

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.

Annotation In the next few decades copper will help to consolidate advances in telecommunications and Internet technology. The outlook for copper is bright, and despite the onset of recession in 2000, demand should pick up from 2002-2003 and return to reasonable industrial growth rates in the developed world. World copper prices are predicted to rise due to the dearth of new mining projects in the economic climate of 2001 and steadily rising metal demand led by China. In order to meet increased demand over the next 10 years there will have to be new mining capacity, including recycling of scrap copper and restarting idled capacity. China showed 13.6% growth in demand up to June 2001 and could overtake the US as the world's number one copper consumer in the next 20 years. Up-to-date, in-depth research and analysis to make you an authority on the world's major copper markets this report gives a clear, objective analysis of the world copper industry as it prepares to take advantage of soaring demand in the electronic, electrical and telecommunications industries. Some key findings of this report: How the output of the world's leading copper mines, Escondida, Chuquicamata and el Teniente is set to change over the next few years and what this means for Chilean and world copper production. Beyond 2003 copper demand will flatten in the mature, developed Western countries: this will leave the market delicately poised, and producers will largely be determining their own destinies when deciding when to commit to new projects. In the second half of this decade copper demand should pick up strongly, feeding fears of a shortfall in supply. Peru's copper output is set to be boosted by 50% through the Antamina mining project, owned by the Canadian consortium of Rio Algom, Noranda, Teck Corp and Mitsui. Telecommunications is a large and growing market for copper: the sector has seen factory sales growing at 8.3% compound rate over the past 8 years, led by strong growth in construction along with the increasing popularity of the Internet. Demand from the automotive sector will also boost consumption of copper in electrical and electronic applications. In 2001 the average copper content of a passenger car was 60lb, compared with under 55lb in 1995.
