Excerpt: ... to become more distinctly so, as the manufacture of Montana coke increases and improves. Bessemer Smelting. The Bessemer plants of the Montana Works constitute their most distinctive feature, and are deserving of special study. The credit, not only of introducing M. Manhes modification of the steel converter to the exigencies of copper smelting, but of applying the process on a large scale, is due to Mr. Franklin Farrel, who, in 1882-3, erected two converters at the Parrot Works, in Butte. At first the operation of making bars consisted of two steps--blowing a 40 to 50 per cent. matte to a grade intermediate between blue and white metal, then casting, re-melting, and blowing this up to metallic copper. The difficulty of the process has always been met, whether by Hollway, or when the convertor was, very early in its history, used in Russia, as soon as metallic copper began to form and chill in the tuyeres. This obstacle M. Manhes combatted, by elevating the tuyeres, and inserting the blast through the side instead of the bottom of the converter. Ultimate success was achieved by so devising the tuyere boxes and tuyeres, that they could be readily reached, when necessary, and rapidly punched. Now the charge of matte is everywhere blown up to metal at one operation. The practice of the four Butte establisments, which convert, does not differ in essential particulars. All use upright converters, which remain stationary during the blow. The largest are those in the Boston and Montana works at Great Falls, which are an exact reproduction of the 15-ton steel convener, except that the tuyeres are elevated 18 inches above the bottom of the shell, so as to be on or above the level of the fresh lining. Three shells are the complement for each...

Available in PDF, EPUB and Kindle. Book excerpt: Over the past two centuries, industrial societies hungry for copper – essential for light, power, and communication – have demanded ever-increasing quantities of the metal. Born with a Copper Spoon examines how the metal has been produced, distributed, controlled, and sold on a global scale. However, this is not simply a narrative of ever-increasing and deepening global connections. It is also about periods of deglobalization, fragmentation, and attempts to sever connections. Throughout history, copper production has spawned its own practices, technologies, and a constantly changing political economy. Large-scale production has affected ecologies, states, and companies, while creating and even destroying local communities dependent on volatile commodity markets. Former president of Zambia Kenneth Kaunda once remarked that Zambians were “born with a copper spoon in our mouths,” but few societies managed to profit from copper’s abundance. From copper cartels and the futures market to the consequences of resource nationalism, Born with a Copper Spoon delivers a global perspective on one of the world’s most important metals.

Book excerpt: This three volume set presents papers from the first collaborative global metallurgy conference focused exclusively on extractive topics, including business and economic issues. Contributions examine new developments in foundational extractive metallurgy topics and techniques, and present the latest research and insights on emerging technologies and issues that are shaping the global extractive metallurgy industry. The book is organized around the following main themes: hydrometallurgy, pyrometallurgy, sulfide flotation, and extractive metallurgy markets and economics.
Download or read book Gambling on Ore written by Kent Curtis and published by University Press of Colorado. This book was released on 2013-07-15 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gambling on Ore examines the development of the western mining industry from the tumultuous and violent Gold Rush to the elevation of large-scale copper mining in the early twentieth century, using Montana as representative of mining developments in the broader US mining west. Employing abundant new historical evidence in key primary and secondary sources, Curtis tells the story of the inescapable relationship of mining to nature in the modern world as the United States moved from a primarily agricultural society to a mining nation in the second half of the nineteenth century. In Montana, legal issues and politics—such as unexpected consequences of federal mining law and the electrification of the United States—further complicated the mining industry’s already complex relationship to geology, while government policy, legal frameworks, dominant understandings of nature, and the exigencies of profit and production drove the industry in momentous and surprising directions. Despite its many uncertainties, mining became an important part of American culture and daily life. Gambling on Ore unpacks the tangled relationships between mining and the natural world that gave material possibility to the age of electricity. Metal mining has had a profound influence on the human ecology and the social relationships of North America through the twentieth century and throughout the world after World War II. Understanding how we forged these relationships is central to understanding the environmental history of the United States after 1850.
