对硼酸盐熔剂对火法精炼废杂铜进行了除铅试验研究，结合电火花直读光谱仪和扫描电子显微镜，分析了硼酸盐熔剂的成分配比和保温时间等因素对废杂铜除铅效果和显微组织的影响，并对其除铅机理进行了探讨。结果表明：当m(B2O3)/m(Na2CO3)=2，保温时间t为30min时，除铅效果最佳，此时除铅率可达86.73%；硼酸盐熔剂的加入明显净化了金属组织。
對硼痠鹽鎔劑對火法精煉廢雜銅進行瞭除鉛試驗研究，結閤電火花直讀光譜儀和掃描電子顯微鏡，分析瞭硼痠鹽鎔劑的成分配比和保溫時間等因素對廢雜銅除鉛效果和顯微組織的影響，併對其除鉛機理進行瞭探討。結果錶明：噹m(B2O3)/m(Na2CO3)=2，保溫時間t為30min時，除鉛效果最佳，此時除鉛率可達86.73%；硼痠鹽鎔劑的加入明顯淨化瞭金屬組織。

The molten borate salt was used as a de-lead agent to remove the lead element of the scrap copper. The effects of composition and holding time on microstructure and deleading percentage of the scrap copper were studied by means of OES and SEM. The results show that when the holding time is 30 min and the mass ratio of B2O3/Na2CO3 is 2, the scrap copper obtain a best lead elimination effect, and the lead elimination rate can reach to 86.73%;Meanwhile, it can significantly purify the microstructure of the scrap copper.
