### WHY A GOLD DEPORTMENT STUDY IS GOOD FOR YOU

Many approaches can be taken to characterize the ore which may occur as complex fine grained gold ultra-fine grained gold coarse nuggety gold and complex As-rich refractory gold. The approach taken will be dictated by the nature of the ore or plant product the amount of sample material available the gold grade and the grain size distribution.

All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it.

The particle-size distributions quoted for gold do not reflect the particle-size distribution of the ore. For example 50 of the gold by weight may exist in a size fraction that only represents 10 of the ore by weight. Also the variation in the weight distribution of gold with particle-size depends upon the nature of the ore
