Take a look inside the KCA Carbon Converter
The KCA Carbon Converter is a modular, self-contained unit which allows you to turn your carbon fines and used carbon into a product you can leach, or smelt directly, to produce a gold/silver bullion.  A three-stage exhaust scrubbing system captures mercury and other volatiles, and final mercury emissions meet emission standards of every US state and foreign country.  The Carbon Converter can treat wet and dirty carbons, turning your “trash” carbon into a valuable resource.  Start processing your carbon on-site and forget about the risks associated with chain of custody.  For more detailed information, download the Carbon Converter brochure.
