Gold sank to the Earth's core during the planet's formation. It's only accessible today because of asteroid bombardment. Theoretically, it's possible to form gold by the nuclear processes of fusion, fission, and radioactive decay. It's easiest for scientists to transmute gold by bombarding the heavier element mercury and producing gold via …

The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold …
