摘　　要：本法基于火试金法的原理，试验将试样不经配料后高温熔融富集，直接在900℃灰吹后，得到金银合粒，再将金银合粒经王水溶解后，原子吸收分光光度计测定，方法简捷快速，可操作性强，结果稳定，降低了对周围环境的污染。After beinghightemperaturemelted and enriched with derict cupellation analysis in 900℃,the assay containing gold and silver is decomposed with aqua regia by fire-assaying method. Then the gold can be measured with flame atomic absorption spectrophotometry. This testing method is simple and convenient, the stable results can be achieved, and also reduced the pollution to the environment.
