Sources of Metals and Acidity at the Elizabeth and Ely Mines

فصل «Sources of Metals and Acidity at the Elizabeth and Ely Mines» از کتاب «Part I. Proterozoic Iron and Zinc Deposits of the Adirondack Mountains of New York and the New Jersey Highlands Part II. Environmental Geochemistry and Mining History of Massive Sulfide Deposits in the Vermont Copper Belt» بر «ذوب مس» در حوزه «متالورژی مس» تمرکز دارد. محتوا مبانی علمی، روش‌های فنی و پیامدهای عملی موضوع را به‌صورت منسجم توضیح می‌دهد. برای انتخاب فرایند، طراحی واحد، تحلیل بهره‌برداری و رفع عیب در استخراج و پالایش مس مفید است.

The Elizabeth and Ely mines are developed in pyrrhotite-rich, Besshi-type massive sulfide deposits in the Orange County copper district of east-central Vermont. Geochemical and mineralogical characterization of historical mine waste and modern flotation tailings show that despite differences in mine site history, the mines share many similarities. Highly soluble efflo-rescent sulfate salts (melanterite, rozenite, chalcanthite) form intermittently on historic mine waste piles and locally on flotation tailings surfaces at both mines and contribute metals and acidity to surface runoff during rainstorms and spring snowmelt.
