The process of Yantai's scrap copper recycling and reuse is worth noting. The variety of scrap copper is complex, and the skills and techniques for recovery and reuse differ. However, it is generally divided into two parts: preliminary treatment and再生 use. Preliminary treatment involves sorting and selecting out mechanical impurities from the thickened scrap copper, removing oil污 from the surface of the scrap copper, and ultimately obtaining single-type, relatively pure scrap copper. This provides the best quality material for smelting and simplifies the smelting process.
Many methods are used for the recycling of scrap copper in Yantai, primarily divided into two categories: direct use of scrap copper and indirect use. Direct use involves melting high-quality scrap copper into refined copper or copper alloys, while indirect use is the process of removing impurities from scrap copper, casting it into anode plates, and then electrolyzing to obtain electrolytic copper.
