Itronics Inc, a “Creative Green Technology Company” that produces GOLD’n GRO fertilizers and silver products, has started research and development to recover tin and copper from the silver bullion being produced by its “Breakthrough Technology” Printed Circuit Board Refining Pilot Plant. Tin was on the list of 35 minerals deemed critical to the US National Security and the Economy published by the US Department of Interior on May 18, 2018.
Itronics President, Dr John Whitney stated, “Our recovery of all of the tin contained on the circuit boards positions the Company to be a world leader in tin recovery from discarded printed circuit boards, a technology advancement of global importance. It also positions Itronics to be the first domestic printed circuit board refiner to recover tin and antimony, making Itronics an emerging domestic critical minerals producer.”
Itronics had previously announced that its technology recovers all the copper, tin, silver, gold, and palladium (palladium is a Platinum Group Metal, PGM) carried on the discarded circuit boards being refined. The technology also recovers all the antimony, which is a fire-retardant mineral that is used to make the circuit boards fireproof. These metals are contained in the Company’s silver bullion which is sold to a finish refiner for separation and sale.
Itronics has performed laboratory testing which indicates that the copper and tin may be separated from the other metals contained in the bullion. The Company will pursue development of this new metal separation technology. The long-term plan is to become a producer of high purity metals, including the strategic metals tin and antimony, using the Company’s hydrometallurgy and pyrometallurgy technologies. Itronics would benefit if the U.S. decides to provide incentives to increase domestic production of “critical minerals,” including tin, antimony, and palladium.
