分银渣中贵金属的提取研究

Study on the extraction of precious metals from silver residue

本文针对分银渣中贵金属的提取研究,结合理论实践,在简要分析分银渣原料成分及物相结果的基础上,探讨了分银渣中贵金属提取的原理及工艺,最后对比论述了湿法和火法提取处理工艺的效果。分析结果表明,在分银渣中贵金属提取中,采用火法处理工艺,效果远大于湿法处理工艺,值得推广应用。

In this paper,based on the study of the extraction of precious metals from silver slag,combined with the theory and practice,the principle and technology of the extraction of precious metals from silver slag are discussed on the basis of the analysis of the composition of raw materials and the results of the phase.At last,the effects of the extraction technology by wet method and fire method are compared.The results show that in the process of extracting precious metals from silver residue,the effect of fire treatment is much better than that of wet treatment,which is worth popularizing.
