Book Description
Due to its inherent characteristics, mercury contamination from gold mining is a major environmental problem compared to past mercury contamination from industrial point sources. The worsening of social-economical conditions and increasing gold prices in the late 1970s resulted in a new rush for gold by individual entrepreneurs for whom Hg amalgamation is a cheap and easily carried out operation. Even after the present-day mining areas are exhausted, the mercury left behind will remain part of the biochemical cycle of the tropical forest. This book reviews the current information on mercury from gold mining, its cycling in the environment and its long-term ecotoxicological impact. The book is illustrated with numerous diagrams and photographs.

Book Description
Exploring the development of California and the relationship between the built environments of the mercury-mining industry and the emerging ethnic identities and communities in California, Mercury and the Making of California brings mercury to its rightful place alongside gold and silver in their defining roles in the development of the American West. In this pioneering study, Andrew Johnston examines the history of California’s mercury-mining industry—and its defining role in the development of the American West. Mercury was crucial to refining gold and silver; therefore, its production and use were vital to creating and securing power and wealth in the west. The first industrialized mining in California, mercury mining had its own particular organization and structure shaped by powers first formed within the Spanish Empire, transformed by British imperial ambitions, and manipulated by groups made wealthy and powerful by controlling it. In addition, the landscapes of work and camp and the relations among the many groups—Mexicans, Chileans, Spanish, British, Irish, Cornish, American, and Chinese—throughout the industry’s history illustrate the complex history of race and ethnicity in the American West. Combining rich documentary sources with a close examination of the existing physical landscape, Andrew Johnston explores both the detail of everyday work and life in the mines and the larger economic and social structures in which mercury mining was enmeshed, revealing the significance of mercury mining to Western history.

Book Description
In Silver by Fire, Silver by Mercury: A Chemical History of Silver Refining in New Spain and Mexico, 16th to 19th Centuries, Saul Guerrero combines historical research with geology and chemistry to refute the current prevailing narrative of a primitive effort dominated by mercury and its copious emissions to the air. Based on quantitative historical data, visual records and geochemical fundamentals, Guerrero analyses the chemical and economic reasons why two refining processes had to share production, creating along the way major innovations in the chemical recipes, milling equipment, mercury recycling practice, and industrial architecture and operations. Their main environmental impact was lead fume and the depletion of woodlands from smelting, and the transformation of mercury into calomel during the patio process.

Book Description
Interest in the title compounds has fallen into three phases: initial study of their solution chemistry, study of their role in the electrode reactions of alkaline batteries during and since World War II, and present concern over the mechanisms by which these elements can enter the environment through dissolution processes, sometimes with toxic results. This volume provides a complete compilation of solubility data published up to 1984, including all pertinent articles, together with critical evaluations of the data. Almost all the measurements relate to aqueous systems.

Book Description
Originally published in 1887, this comprehensive study of the metallurgy of precious metals is a valuable resource for historians, chemists, and mining professionals alike. Egleston thoroughly covers the processes of extraction, refining, and assaying used in the United States at the time, and includes detailed descriptions of the equipment and techniques involved. This book offers a fascinating glimpse into the mineral processing industry in the late 19th century, and provides a starting point for research into more modern methods of extraction.
