I want to know the answer to the following question:
When did The Norddeutsche Affinerie electroplating plant first begin production?
All the background I'm provided with is that "The German scientist Gottfried Osann invented powder metallurgy in 1830 while determining the metal's atomic mass; around then it was discovered that the amount and type of alloying element (e.g., tin) to copper would affect bell tones.". Is that enough to answer the question?
Answer: yes
