Our silver is reclaimed from X-ray film waste. Our partner in Bogotá focuses on buying, recovering and reclaiming metal scrap. The silver is purified to its natural state for then being sold to jewelers. On average 4,5 kg of medical x-ray film contain one troy ounce (31 grams) of pure silver. The most common technique to extract silver from medical x-ray material is through electrolysis.
Note We aim to keep on improving our practices and the way we document them. If there is something you would like to know or suggest, please tell us at about@aluna.fi.
