Recycling scrap metal requires further processing, utilizing electrolytic silver recovery equipment. The cathode is made of graphite plates, while the anode is an不锈钢 roller. Sodium citrate and sodium sulfite serve as the electrolyte. Silver-plated parts enter and exit from the roller's ends. The silver on the surface of the recycled scrap metal parts is immersed in the electrolytic bath, ensuring the base material is not damaged and can be reused in new plating processes. Additionally, the recycling and application of scrap silver-zinc batteries in metal recycling. Zinc is the negative electrode, coated on a copper mesh frame, while the positive electrode is silver-painted. Zinc and copper are separated using dilute sulfuric acid, and silver powder is used to indirectly smelt ingots. The dilute sulfuric acid leaching of copper contains an oxidizing agent, while the concentrated crystallization of the zinc-containing liquid consumes zinc sulfate and the concentrated crystallization of the copper-containing liquid consumes copper sulfate.
