💎Gold bars can be repurposed into high purity gold powder through re-purification.
🔬The re-purification process involves dissolving gold bars in hydrochloric acid and nitric acid.
🧪Impurities are separated from the gold solution using precipitation techniques.
💧Sodium metabisulfite is used to precipitate the gold as a powder.
🚿The gold powder is rinsed multiple times to remove excess chemicals and collect the purified gold.
