Electrolytic recovery of gold from aqueous

Electrolytic recovery of gold and copper from gold alloy electrolytes. 3 shows, the recovery rate of gold is higher than that of copper. Examination of Figs 2 and 3 reveals, that the recovery of gold from dilute solutions using the electrolytic reactor yields high deposition rates. This, therefore, provides a unique industrial application, where gold recoveries as low as 0.1 mg I - can be

Tin(II) chloride - Wikipedia

Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula Sn Cl 2.It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot.SnCl 2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating.Tin(II) chloride should not be confused with the other chloride of tin; tin(IV) chloride
