Toma Group started it’s eco-recycling by adopting technology of basic alloys which had only 2 elements: either W-Re or Mo-Re. This technology has developed over years to meet clients expectations in yield, speed and quality. As result client receives W or Mo oxide as by-product in form of dry powder and Ammonium Perrhenate with purity higher than Catalyst Grade. Any physical form of such scrap can be recycled. Main refining part is done in pyrometallurgical oxidation furnaces with no air or water pollution.
