The most appropriate method of analysis for each individual sample supplied will be assessed, based on the Laboratory’s knowledge and technical expertise.
Typical methods of gold analysis:
- Fire Assay Collection: Traditional Fire Assay cupellation (following the principles of ISO 11426) and a gravimetric or spectrometric finish depending upon the concentration of gold in the sample/solution.
- Fire Assay – ICP-OES technique for low to medium grade powder/ore samples: A fusion collection, followed by cupellation, dissolution of the precious metal bead in an appropriate acid matrix and final determination by ICP-OES.
