Production of Gold - West Virginia University

pure and are submerged with 99.9% pure rolled gold cathodes in an electrolytic solution with 100g/L each of gold and hydrochloric acid. A current density of 800 A/m2 is applied at 60°C, and the gold collected on the cathodes is rinsed several times with a hot sodium thiosulfate solution before the 99.9% pure cathodes are melted and recast as final

Sodium thiosulfate can also be used instead of sodium arsenite. Add small portions (0.02 g/L), with re-testing after each addition. Do not add excess sodium thiosulfate. To determine chlorine < 2 mg/L use a DPD colourimetric method (APHA 4500-Cl.G) and add a stoichiometric amount of sodium thiosulfate solution (APHA 4500- Cl.B.2d). Note: If the ...
