    merrill crowe gold recovery

    Another SO 2 scrubber example is gas cleaning equipment for a mineral processing application to recover gold and silver from mine sites with low grade ore. Discovered and patented in the early 1900 by Charles Merrill and later refined by Thomas Crowe, the Merrill-Crowe process is a common separation technique for removing gold and silver from a cyanide solution using zinc dust.
