RENO, Nev., April 17, 2018 (GLOBE NEWSWIRE) — Itronics Inc. (OTC:ITRO), a diversified zinc, fertilizer and silver producing green technology development Company, today announced that its new commercial scale e-scrap grinder in tests is producing significantly more bullion (from computer scrap).  This greatly increases the chances of Itronics being able to produce and sell more silver, gold and copper in the short term and tin and palladium over the longer term, all derived from computer wastes.   The prices of every one of these metals increased significantly in 2017 and Itronics is poised to take advantage of continued price hikes.
