Race and Labor in Western Copper

Race and Labor in Western Copper

Philip J. Mellinger

This is the story of immigrant copper workers and their attempts to organize at the turn of the century in Arizona, New Mexico, Nevada, Utah, and El Paso, Texas. These Mexican and European laborers of widely varying backgrounds and languages had little social, economic, or political power. Yet they achieved some surprising successes in their struggles all in the face of a racist society and the unbridled power of the mine owners. Mellinger's book is the first regional history of these ordinary working people miners, muckers, millhands, and smelter workers who labored in the thousands of mountain and desert mining camps across the western heartland early in this century. These men, largely uneducated, frequently moving from camp to camp, subjected to harsh and dangerous conditions, often poorly paid, nevertheless came together for a common purpose. They came from Mexico, from the U.S. Hispanic Southwest, and from several European countries, especially from Greece, Italy, the former Yugoslavia, and Spain. They were far from a homogeneous group. Yet, in part because they set aside ethnic differences to pursue cooperative labor action, they were able to make demands, plan strikes, carry them out, and sometimes actually win. They also won the aid of the Western Federation of Miners and the more radical Industrial Workers of the World. After initial rejection, they were eventually accepted by mainstream unionists. Mellinger discusses towns, mines, camps, companies, and labor unions, but this book is largely about people. In order to reconstruct their mining-community lives, he has used little-known union and company records, personal interviews with old-time workers and their families, and a variety of regional sources that together have enabled him to reveal a complex and significant pattern of social, economic, and political change in the American West.
Electromagnetic Absorption in the Copper Oxide Superconductors

Electromagnetic Absorption in the Copper Oxide Superconductors

In 1987 a major breakthrough occurred in materials science. A new family of materials was discovered that became superconducting above the temperature at which nitrogen gas liquifies, namely, 77 K or –196°C. Within months of the discovery, a wide variety of experimental techniques were brought to bear in order to measure the properties of these materials and to gain an understanding of why they superconduct at such high temperatures. Among the techniques used were electromagnetic absorption in both the normal and the superconducting states. The measurements enabled the determination of a wide variety of properties, and in some instances led to the observation of new effects not seen by other measu- ments, such as the existence of weak-link microwave absorption at low dc magnetic fields. The number of different properties and the degree of detail that can be obtained from magnetic field- and temperature-dependent studies of electromagnetic abso- tion are not widely appreciated. For example, these measurements can provide information on the band gap, critical fields, the H–T irreversibility line, the amount of trapped flux, and even information about the symmetry of the wave function of the Cooper pairs. It is possible to use low dc magnetic field-induced absorption of microwaves with derivative detection to verify the presence of superconductivity in a matter of minutes, and the measurements are often more straightforward than others. For example, they do not require the physical contact with the sample that is necessary when using four-probe resistivity to detect superconductivity.
The Legacy of American Copper Smelting

The Legacy of American Copper Smelting

Throughout world history, copper has been a significant metal for a vast number of cultures, from the oldest civilisations on record to the Bronze Age and Greek and Roman antiquity. Though replaced by iron as the primary metal for tools and weapons in ancient civilisations, copper found new resurgence in the nineteenth century when it was discovered to have particularly high thermal and electrical conductivity. Copper mining quickly escalated into a large-scale industry, and because of its vast reserves and innovative mining techniques, the United States seized the reins of global production with the opening of significant copper mines in Tennessee and Michigan in the 1840s and Montana in the 1870s.Copper-mining prosperity and America’s dominance of the industry came with a heavy environmental price, however. As rich copper deposits declined with increased mining efforts, large deposits of leaner ores—oftentimes less than one percent pure—had to be mined to keep pace with America’s technological thirst for copper. Processing such ore left an inordinate amount of industrial waste, such as tailings and slag deposits from the refining process and toxic materials from the ores themselves, and copper mining regions around the United States began to see firsthand the landscape degradation wrought by the industry.In The Legacy of American Copper Smelting, Bode J. Morin examines America’s three premier copper sites: Michigan’s Keweenaw Peninsula, Tennessee’s Copper Basin, and Butte- Anaconda, Montana. Morin focuses on what the copper industry meant to the townspeople working in and around these three major sites while also exploring the smelters’ environmental effects. Each site dealt with pollution management differently, and each site had to balance an EPA-mandated cleanup effort alongside the preservation of a once-proud industry.Morin’s work sheds new light on the EPA’s efforts to utilise Superfund dollars and/or protocols to erase the environmental consequences of copper-smelting while locals and preservationists tried to keep memories of the copper industry alive in what were dying or declining post-industrial towns. This book will appeal to anyone interested in the American history of copper or heritage preservation studies, as well as historians of modern America, industrial technology, and the environment.

In Donald J. Trump and China John F. Copper examines President Trump’s views of China that developed before and after he entered office. As a businessman and as a witness to US politics and foreign policy, Trump realized China was the most important country in the world to the United States. He also recognized that one of the key difficulties in American trade policy was the imbalance between the US and China. Copper argues that Trump blamed policy makers for the disparity and was determined to rectify the imbalance. President Trump undertook formulating a new China policy in spite of nonsupporters in the Democratic Party, the media, academia, and Hollywood. Donald Trump accepted China’s rise as an economic power and felt he could negotiate with President Xi to construct a positive relationship that would benefit both countries, save the global financial system, curb nuclear proliferation, and save the environment. Ultimately, Copper asserts that Trump knew a constructive relationship with China would be challenging, however he also understood that this is the nature of big power politics and strategic negotiations and realism would ensure peace between these two powerful countries.
