Fire Assay Preconcentration-Gravimetric Method to Determine Gold and Silver in Copper Concentrate
The authors studied a new fired fusion furnace and fired cupellation furnace in the gold and silver content in copper concentrate detection and the application of the gravimetric method, and the detection efficiency of the gold and silver content in copper concentrate was greatly improved, and a fast determination of copper concentrate in large sample batches could come true. The method was characteristic of easy, fast and high accuracy.
