Gold mining uncovers more and more hydrothermal deposits in which gold mineralization is associated with sulfides and other compounds of base metals, arsenic, antimony, or tellurium. This type of mineralization frequently makes gold recovery difficult by conventional techniques, such as amalgamation, gravity separation, or direct cyanidation.
