    Discussion of the influence of impurity elements on the determination of gold content in coarse gold by fire assay gravimetric method……Ma Lijun,LiZhengxu,Zhong Yingnan,Kan Chunhai,Xiao Qianpeng,Zhao Kedi

    AbstractThe influence of impurity elements on the determination of gold content in coarse gold by fire assay gravimetric method is discussed,and a series of tests are conducted to determine the upper limit of the method applicable to the 12 impurity elements:Cu,Fe,Zn,Ni,Pt,Pd,Se,Te,Sb,Bi,Tiand W and the measures to ensure the applicability of the method when impurity elements surpass the upper limit.The study has great significance in guiding gold smelting enterprises to carry out accurate determination of gold contentin coarse gold.

    Keywords:coarse gold; fireassay; gravimetric method; impurity; increment
