  • Cyanide Regeneration Processes and Methods

    Cyanide regeneration offers a practical means of overcoming the otherwise heavy cyanide consumption frequently encountered in the treatment of gold and, especially, silver ores, where cyanicides (cyanide consuming minerals) are present. Miscellaneous processes used for the extraction of gold and silver values by hydrometallurgical means are also discussed in this chapter.
