    Reaction of gold with acids. Gold metal dissolves in aqua regia, a mixture of hydrochloric acid, HCl, and concentrated nitric acid, HNO 3, in a 3:1 ratio. The name aqua regia was coined by alchemists because of its ability to dissolve gold the "king of metals". Reaction of gold with bases. Gold .

    In this technique, the gold extraction is done under mild conditions, while the solution dissolves gold at the fastest rate ever recorded. "Gold is stripped out from circuits in about 10 seconds, leaving the other metals intact," Foley said. Foley said it requires 5,000 litres of aqua regia to extract one kilogram of gold from printed circuit boards, none of which can be recycled. With the new ...

  • Cyanide Leaching Of Gold

    Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal. Chemically, it is a rather simple reaction: 4 Au + 8(NaCN) +O2 + 2 H2O = 4 NaAu(CN)2 + 4 NaOH That presumes ...

     · When oxidation–reduction reactions occur in aqueous solution, however, the equations are more complex and can be more difficult to balance by inspection. Because a balanced chemical equation is the most important prerequisite for solving any stoichiometry problem, we need a method for balancing oxidation–reduction reactions in aqueous solution that is generally applicable.
