Itronics Reports Positive Results From KAM-Thio Tests to Recover Silver, Gold and Neutralize Cyanide From Leached Mine Tailings

Itronics (OTC:ITRO), a diversified producer of GOLD’n GRO zinc fertilizers and silver products and a green technology development company today reported positive results from initial testing of its KAM-Thio technology on silver-gold heap leach tailings.

Itronics proprietary silver recovery technology, which is used to remove silver from spent photographic liquids, is then used to treat the KAM-Thio leaching solution to remove silver, gold, and base metals from the liquid. The metals were successfully removed and the leach solution was partially regenerated by the metal removal process, thereby reducing consumption of KAM-Thio liquid, further validating the effectiveness of this “Breakthrough” technology in the mining application.

Dr. John Whitney, Itronics President, said:

“These preliminary results are very positive and provide justification for continuing the work. Process economics have not yet been evaluated, but analysis done to date indicates that KAM-Thio consumption may be relatively modest.

Most importantly, results obtained to date indicate that the residual silver, gold, base metals, and cyanide can be removed from the cyanide leached ore by the KAM-Thio leaching solution and that the leached silver, gold, and base metals can be completely recovered from the leaching solution.”
