Because much more of the silver in the Round Mountain ore occurs in manganese mineral than the Candelaria ores, sulfur dioxide-sodium chloride leach must be used for ores which contain substantial amounts of manganese. Silver was recovered from the leach solutions generated in these experiments by precipitation using zinc or iron dust.
