✨Hydrogen peroxide can be used as an oxidizer to release gold from sulfides.
❌The use of hydrogen peroxide for sulfide oxidation is not economically viable due to the large amount required.
🔥Creating a glassy, acidic slag can prevent the formation of matte and facilitate the recovery of precious metals.
🧪Adding iron to the smelting process can replace copper and lead sulfides and improve the recovery of precious metals.
🌋Controlling the composition of the slag is crucial to optimize the recovery of precious metals during smelting.
