Book excerpt: Excerpt from Losses in Gold Amalgamation: With Notes on the Concentration of Gold and Silver Ores The variety of modifications in approved pro cesses to which reference is made, ought at least to suggest the desirability of exhausting the known before drawing on the unknown and purely specu lative. It should also be borne in mind, that what might appear at first sight to be new processes, and even new machinery, are in fact, often nothing but Old contrivances and plausible theories long ago exploded among practical men.

This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Gold has been known from the earliest ages, from its occurrence in a metallic state in sedimentary deposits as well as in veins. "On account of its great specific gravity, it can be collected from placers and river beds, by separation with water alone, and in veins after the matrix is crushed, a great amount is saved by the same simple method. When only rich deposits were exploited, anybody could manage as it apparently required only labor and opportunity, while as long as money was made, the losses that occurred did not trouble the owners. From this very simplicity of working, the majority of owners and investors imagined that no special training was requisite to insure success, but that any trustworthy man, skilled in mercantile pursuits, was the proper person for the place of general manager. To-day the same opinion is held by very many, in spite of the warnings from hosts of disastrous failures. One cause for this belief has been the lack of literature for this special branch of metallurgy; in fact, very near 1890, there was practically no works written at all which spoke of gold except as a subsidiary product of the metallurgy of other metals. Volumes, both practical and scientific, have been published which deal with the special branches of the metallurgy of lead, copper, and silver, but the metallurgy of gold seemed so simple, it only required an occasional article in a paper or magazine. In spite of this dearth of written knowledge, practical men in all parts of the world were rapidly improving the methods of treatment, both mechanically and with the aid of chemistry, in their several localities; but, through lack of exchange of thought, each section had a different process, on which faith was pinned to the...
