The CEO of GreenFence–MetalLogic S.A., Angelos Ginis, returned to the National Technical University of Athens (NTUA) for the fourth consecutive year, delivering a lecture titled: “Precious Metals Refining from Jewelry Scrap.”
Through practical examples and case studies, he shared know-how and best practices for the sustainable recovery of gold and silver from jewelry scrap, highlighting the importance of proper sampling, material balance, and compliance with international standards.
Warm thanks to Professor Anthimos Xenidis for the hospitality, and to the students for their attention and vibrant engagement throughout the discussion.
The lecture concluded with a short FAQ-quiz, inviting attendees to keep the conversation going beyond the classroom:
-
Will the price of gold/silver go up?
-
Should I invest in gold?
-
Gold or silver — which investment makes more sense?
-
Is it worth buying gold sovereigns or gold bars?
