Abstract:The experimental conditions for the determination of gold content in quartz sand by fire assay gravimetric method are studied, and the batching scheme for the melting of fire gold test, the effect of silver content in the sample on gold separation, the error sources of gold content determination by gravimetric method and atomic absorption method are investigated. The experimental results show that the method has good precision and accuracy. The application range of this method is between 1.0g/t and 10.0g/t.
