Book excerpt: Excerpt from The Practice of Ore Dressing in Europe: A Description of Foreign Methods for the Mechanical Concentration of Ores, Revised and Corrected From a Series of Articles in the School of Mines Quarterly of Columbia College A Visit to the ore dressing establishments of Europe and a comparison of their several methods of working discloses the great development which the mechanical treatment of ore has undergone during the past few years. Some of the works have remained almost unaltered since the date of their erection, twenty years ago; others have been enlarged or modified in accordance with advanced ideas, and sometimes exhibit the old and the new side by side; and others, again, have but recently been erected and embody many of the improvements derived from experience. To note the advances that have been made in ore dressing may prove of interest to some, and would certainly possess practical value if suggesting the direction in which further improvements will be sought. Most conducive to this object would be a study of the schemes of ore treatment that have been developed in the various mills; but this method, unless thoroughly carried out - a proceeding which would far exceed the limits here proposed - can lead to no useful results: any scheme or synopsis of an ore treatment not supplemented by an accurate description of the ore, and by accounts of the disposition made of the various mill products, and by a complete statement of local conditions, including many small, yet influencing details, will always prove very unsatisfactory. Remarks of a general nature have therefore been preferred, and these (restricted so as not to embrace the subject of coal washing) present a digest of matter that has been gathered in the foreign mills through the kindly courtesy of their owners and managers.
