Intended to "offer a little useful knowledge to directors of English gold mining companies on some of the simple principles that are too often ignorantly, or designedly, ignored, or surrounded with mystery by inexperienced mine managers; also to give to millmen a few suggestions, founded on a tolerably wide experience, in the commercial handling of many kinds of ores." - from Preface. Text divided into the following parts: Losses in Gold Amalgamation; Treatment of Gold Ores; Concentration of Gold and Silver Ores; Methods of Concentration. Prior owner's details in pencil upon front free endpaper else unmarked. Binding intact. Minor foxing. Red cloth covers soiled and stained with above-average wear - gilt lettering still legible. A worthy copy of this practical vintage work.
