| Description |
Fire assay is the most common technique for the determination of precious metals in rock and
ore samples. and is generall! accurate for the determination of gold. However with the
development of modern laboratory techniques such as Inductively Coupled Plasma-Optical
Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma-Mass Spectrometry (ICPMS).
alternatile methods have become available which offer the advantages of rapid
determination of small concentrations of gold in a number of samples for preliminary exploration
studies. A multi-parametric linear regression model was used to estimate the obsered
interferences and using this model. the gold content in ores has been estimated. A simple
analytical method for the determination of gold in ore samples using ICP-OES is reported and
these results show that this method can be successfully applied when the gold concentration
high (above 0.7ppm) with an error in the range of 9-11% in ore samples. The advantage of this
method over conventionally adopted Fire Assay is small sample size and larger sample
throughput.
