Cyanide-free mild chloride leaching was investigated. •. Gold could be recovered even at <520 mV vs. Ag/AgCl in carbon-in-chloride-leach mode. •. Copper was a stronger oxidant than iron in gold leaching. •. Gold was oxidized by in-situ dissolving impurities. •. Seawater contains enough chlorides to dissolve gold.
The gold leaching rate increased with the increase in temperature and reached 73.7% at 1100 °C, which was 68.27% higher than that of untreated ore. The increase in gold leaching rate was attributed to two reasons. One was the effective dissociation of locked gold, which increased the contact and dissolution between gold …
The atmospheric leaching setup enables a permanent supply of oxygen, which not only facilitates the gold oxidation but also increases thiosulfate decomposition at the same time.
The diverse uses of gold and its crucial role in the global economy are growing, particularly during cycles of economic crises. The broad use of cyanide by conventional gold-mining companies and mercury by artisanal miners poses environmental and health concerns for local communities. This article introduces an innovative gold …
