silver extraction refining
Silver processing
Silver processing - Refining, Alloying, Uses: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone …

Is it potentially worthwhile to remove the plating from ~50kg of silver
There is no known method of removing and refining silver plating that is in the least way profitable, once all costs are considered. If your goal is to refine recovered copper, an industrial scale copper refinery can be profitable, with silver as a bonus. My preferred use of silver plated copper is cementation of silver from solution.
