AN ENVIRONMENTALLY FRIENDLY WAY TO MINE FOR GOLD
Using test tube chemistry, a chance discovery by a researcher in Fraser Stoddart's lab led to a cheap and environmentally friendly process for mining and extracting gold. This environmentally benign method uses a sugar derived from cornstarch – instead of cyanide – to isolate gold from raw materials in a selective manner. The process is simple, selective, scalable and highly cost efficient. All it requires is for the gold-bearing materials to be dissolved in an aqueous solution that is relatively safe and easy to handle – unlike the current cyanide leaching process used in 80% of today's gold production.
Join Dr. Stoddart as he presents the results of this research. It is a piece of magic for isolating gold from any source – in a green way.
You can order and eat dinner during the presentation. The burgers are great!
