  • Electrolytic Refining: Silver Gold Copper

      The electrolytic process of goldrefining possesses three advantages that are important in mintwork First, it produces purer gold than the old processes The elimination of the last trace of silver from the gold removes the brittleness from the ingots used for coinage, so that they roll and press much better than alloys of the same fineness in gold, but made of slightly impure goldAn electrolytic silver refining process in which crude silver is anodically dissolved and refined silver is cathodically deposited and at the same time accompanying metals are selectively extracted from the spent electrolyte and separately cathodically deposited after having been transferred into an aqueous phase and the regenerated electrolyte stripped of accompanying metals is recycled to the silver Electrolytic silver refining process Ogussa In an electrolytic silver refining process, crude silver is anodically dissolved while refined silver is cathodically deposited and at the accompanying (impurity) metals are selectively extracted from the used (spent) electrolyte and transferred to an aqueous phaseElectrolytic silver refining process and apparatus

  • Challenges in the Electrolytic Refining of Silver

      Due to the high standards for silver in electronic uses, it is essential to control the behavior of the main impurities such as copper or palladium during the electrolytic refining In regard to palladium, it is indispensable to control its complete transition into the anode slime  The ultimate goal of the process improvement is to reduce the necessary metal stock while ensuring the required product purity In silver refining electrolysis, Pd is a challenge which shall not be underestimated as the standard 2 Hydrolysis can occur during the washing process of fine silver, and therefore be accordingly eliminated by washing withChallenges in the Electrolytic Refining of Silver Beginners better try the electrolytic method Usually silver is refined from the contacts in this way The procedure consists of 3 stages This is the dissolution of silver in nitric acid, its cementation and fusion, and directly refining silver at home by electrolysisSilver refining: at home The science 2021
