Electrometallurgy and Environmental Hydrometallurgy, Volume 2 - Extraction of Copper at Elevated Feed Concentrations

این کتاب در فیلد «متالورژی مس» و زیرموضوع «استخراج حلالی مس» قرار می‌گیرد. محورهای قابل تشخیص از عنوان و متادیتای Lens عبارت‌اند از: هیدرومتالورژی، استخراج حلالی، هیپ‌لیچینگ، لیچینگ. این منبع مستقیماً بر یکی از اجزای زنجیره ارزش مس تمرکز دارد. برای شناخت و طراحی فرایندهای استخراج، ذوب، پالایش، لیچینگ، استخراج حلالی و الکترووینینگ قابل استفاده است. این متن یک خلاصه موضوعی فارسی بر پایه متادیتای موجود است؛ چکیده انگلیسی، در صورت وجود، در ستون جداگانه حفظ شده است.

A number of flowsheets have been designed and operated, or are currently being considered, to extract copper from leach solutions having much more copper than the 4 g/L levels typically found in heap leach liquors. Dealing with these solutions has required that the envelope for “normal” copper solvent extraction be pushed beyond the usually considered limits. Others have published information on flowsheets to recover copper from leach liquors containing over 25 g/L copper. Secondary solvent extraction circuits are often required to attain satisfactory overall recoveries. This paper reviews some of the issues faced in three pilot plant circuits that were operated by SGS Lakefield Research to produce cathode copper from solutions containing 8 to 20 g/L Cu. The primary objective was to maximize copper extraction using one solvent extraction circuit. The role of feed acidity and the disposition of impurities such as iron and chloride are considered. The challenges of running short SX piloting campaigns are discussed.
