Recovery of Valuable Metals from High-Content Arsenic Containing Copper Smelting Dust

فصل «Recovery of Valuable Metals from High-Content Arsenic Containing Copper Smelting Dust» از کتاب «The Minerals, Metals & Materials Series» موضوع را در حوزه «متالورژی مس» بررسی می‌کند. محتوا به لیچینگ کانسنگ می‌پردازد. برای انتخاب فرایند، طراحی واحد، تحلیل بهره‌برداری و رفع عیب در استخراج و پالایش مس مفید است.

Smelting-acid leaching process is a way to treat high-content arsenic containing copper. However, smelting process makes a low recovery of valuable metals and acid-leaching process makes large amounts of arsenic-iron slag. Arsenic sulphuration volatilization at a low temperature was studied in this paper and valuable metals were recovered with different methods. Arsenic recycled as As2O3 was separated from other valuable metals selectively and calcines were treated by acid pressure leaching. Indium and copper in leaching liquor were made into sponge indium/copper after the processes of extraction-re-extraction-displacing process (ERD process) and displacing process.
