W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001 4 The Future. The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching "oxide" and supergene sulfide ...
Contact usExtract copper and gold from low-grade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 15-20 per cent of the world''s current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation.
