What makes this book unique is a specific focus on aluminum recovery, rather than just recycling in general. It also offers an integrated discussion of scrap recovery and re-melting operations and includes economic as well as technical elements of recycling. Important topics include a discussion of the scrap aluminum marketplace and how secondary aluminum is collected and sorted, the design and operation of furnaces for melting scrap, the refining of molten aluminum, and the recovery and processing of dross from re-melting operations. This second edition features more information on aluminum scrap pricing and the economics of recycling, the analysis of dross processing methods currently in use by the industry, and drosses produced. The book has been updated throughout to include the most up-to-date information.
A completely revised and up-to-date edition containing comprehensive industrial data. The many significant changes which occurred during the 1980s and 1990s are chronicled. 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 volume targets the recycling of copper and copper alloy scrap as an increasingly 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.
Coming to understand Mark Schlesinger's canvases--any one of them--demands a degree of sustained attention, reflection, and interpretation that prohibits generalization and reduction. Each painting is a world. [Each] needs to be seen time and again, described and discussed time and again [...] It is equally clear that Schlesinger's [pictorial] logic of touch is analogous to human contact, and to the meaning contact generates and is felt to bring to one's separate self [...] In Schlesinger's art, painting transforms prosaic communication into an elevated pictorial expression of responsive seeing and feeling.
The past few decades have brought significant advances in the computational methods and in the experimental techniques used to study transport phenomena in materials processing operations. However, the advances have been made independently and with competition between the two approaches. Mathematical models are easier and less costly to implement, but experiments are essential for verifying theoretical models. In Mathematical and Physical Modeling of Materials Processing Operations, the authors bridge the gap between mathematical modelers and experimentalists. They combine mathematical and physical modeling principles for materials processing operations simulation and use numerous examples t...
This text takes a practical approach to its presentation of stoichiometry and energy-balance principles for materials engineering students by emphasizing their use in actual engineering practice.
Patients as Policy Actors offers groundbreaking accounts of one of the health field's most important developments of the last fifty years--the rise of more consciously patient-centered care and policymaking. The authors in this volume illustrate, from multiple disciplinary perspectives, the unexpected ways that patients can matter as both agents and objects of health care policy yet nonetheless too often remain silent, silenced, misrepresented, or ignored. The volume concludes with a unique epilogue outlining principles for more effectively integrating patient perspectives into a pluralistic conception of policy-making. With the recent enactment of the Patient Protection and Affordable Care Act, patients' and consumers' roles in American health care require more than ever the careful analysis and attention exemplified by this innovative volume.
This distinguished collection stands out from the recent flurry of books on health reform by its sustained and sophisticated analysis of the political dimension. In The Politics of Health Care Reform, some of America's best-known political scientists, historians, and legal scholars make sense of our most turbulent policy issue. They dig below the jargon and minutiae to explore the enduring questions of American politics, government reform, and health care. The Politics of Health Care Reform explains how successful reforms occur in the United States and shows what is unique about health care issues. Theoretically informed, politically astute, historically nuanced, this volume takes an invento...
"Examines the private nonprofit sector and the tax-exempt institutions that make up this sector providing important services and benefits to all Americans, with histories behind different institutions and the forces and developments that have buffeted them and what they have done to retain their resilience"--Provided by publisher.
