火法测定金渣中金银配料比的试验研究

Study on the Mixture Ratio of Solid Reagents in Gold and Silver of Solid Waste by Fire Method

针对金渣中贵金属金银的测定,通过条件试验确定了试样熔融配料比,进行了精密度、准确度试验。得到:熔融固体试剂氧化铅、碳酸钠、二氧化硅、硼砂、面粉的加入量分别为80 g、40 g、18g、10 g、3 g时,铅扣沉降完全、质量合适,熔渣流动性好。在此配料方法下,测定结果精密度好,准确度高。

In view of the determination of gold and silver of precious metal in gold slag,the mixture ratio of solid reagentsthe for sample melting was determined by condition experiment,and the precision and accuracy were tested.When the melting solid reagents,as lead oxide,sodium carbonate,silica,borax and flour,were added to 80 g,40 g,18 g,10 g,3 g,the lead buckle was completely deposited,the quality of it was suitable and the fluidity of slag was good. Under this method,the precision and accuracy of the determination are good.
