Itronics Starts R&D to Recover Tin, a U.S. Critical Mineral, and Copper From Silver Bullion Produced by Its “Breakthrough Technology” Printed Circuit Board Refining Pilot Plant

RENO, Nev., Jan. 15, 2019 (GLOBE NEWSWIRE) -- Itronics Inc. (OTC:ITRO), a “Creative Green Technology Company” that produces GOLD’n GRO fertilizers and silver products, today announced that it 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 U.S. National Security and the Economy published by the U.S. 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.

According to the U.S. Department of Interior, there is no mine production of tin in the United States.  All the new tin that is required by the U.S. economy is imported.  The most important foreign countries in order of importance that supply tin to the United States are Indonesia, Peru, Malaysia, Bolivia, and Brazil.

The list of critical minerals was published in response to a White House Executive Order issued on December 20, 2017 for the purpose of reducing the United States dependency on imports of critical minerals.  Under the Executive Order, a “critical mineral” is defined as “a non-fuel mineral or mineral material that is essential to the economic and national security of the United States, that has a supply chain vulnerable to disruption, and that serves an essential function in the manufacturing of a product, the absence of which would have significant consequences for the economy or national security.”

Itronics is now operating its breakthrough printed circuit board refining technology, which refines circuit boards extracted from e-waste, on a pilot scale at its manufacturing plant in Reno, Nevada.  The circuit boards are converted into energy which is used in the refining process, and silver bullion and silver-bearing glass which are sold, thereby eliminating the waste from the environment.

Itronics has pioneered the development of “Zero Waste” material recovery technology that converts liquid photochemical waste into silver bullion and a “non-nutrient metal free” liquid ingredient used to manufacture the line of high quality GOLD’n GRO liquid fertilizers.  Dr. Whitney said:  “Itronics is now pioneering and has achieved operational proof of concept for its second ‘Zero Waste’ material recovery technology, the breakthrough printed circuit board refining technology which is now being operated at a pilot scale.”
