This attractive method of separating gold from silver has made some headway and will in many cases replace other methods of parting The electrolyte used is a solution of silver nitrate or it may be started with dilute nitric ac The cathode consisting of thin silver plate and the anode of the silver gold alloy usually in plates about 3/8 inch in thickness The electrolyte vats consist of electrowinning size quantity and weight of cathode mesh is the metal from the eluate solution The anode rectifier complex robust and easy to operate unit having calculated plates are fabricated from stainless steel The anodes are connected to an insulated

8/10/ 32 The silver bullion bar turned dark almost blackish by the end of the first run I fire clean between runs but the silver rod cathode only seemed to tarnish slightly by the end I just wanted to know if I am doing something wrong or if it is normal for the silver rod cathode to seem to be reacting and micro bubbling instead of the bullion anode The cathode negative lead is the item being plated The current flows from positive to the negative resulting in the copper coating the cathode If we were using AC voltage at sixty cycles for example the copper anode would become the cathode sixty times a

Electrowinning is most commonly used to recover gold silver copper cadmium and zinc Gold and silver are the most successfully recovered metals because of their high electropotential Chromium is the only metal commonly used in electroplating that is not recoverable by electrowinningRESOURCE BOOK Introduction Electrowinning and smelting are the final stages of gold production The concentrated gold solutions produced in the elution circuit pregnant eluate and by the Sunrise Reactor are passed through the electrowinning cells which

The object studied is production solution obtained during cyanide leaching of gravitation concentrates containing about 95 g/m³ of gold 30 g/m³ of silver and 65 g/dm³ CN Silver The electrolytic silver refining process includes a crude silver anode and a refined silver cathode The electrolytic process is similar to gold except that the silver anodes are dissolved in a nitric acid bath The resulting silver will be about 999 pure

For the cathode I attached a 25g piece of pure gold with the idea that I could keep the gold solution concentration consistently full and continue to reuse it I washed the nickel plated piece and then proceeded to plate applying 6 volts solution called for 5 8V silver filled epoxy can undergo dissolution creating Ag ions with presence of moisture and ionic contaminants such as traces of chlorine or bromine Once this occurs a dc electric field between the anode and cathode will pull the silver Ag ions across to the

Anode and cathode refining Purchasing process Purchasing and refining of silver anodes cathode grids sputter targets ESG purchases new and used silver anodes directly We also buy gold silver platinum or palladium coated cathodes or cathode grids I ve also alternated the anode and cathode periodically by reversing polarity of the battery Hence my recommendation to use silver for the anode you get 2 electrodes at once In this way

it is also possible to recover silver and gold from the anode slimes by first dissolving the less noble anode impurities in acid and then casting the remaining noble metals into anodes for subsequent electro refining In many cases the value of the noble metals 2RESOURCE BOOK Introduction Electrowinning and smelting are the final stages of gold production The concentrated gold solutions produced in the elution circuit pregnant eluate and by the Sunrise Reactor are passed through the electrowinning cells which
