The difference here is the faster settling fine material is being pulled toward the exit first. This means that as the bin is emptied there will be less and less fine material in the feed.

However, on rare occasions gold is visible in rock. These ores are generally considered "high grade." Another term that the old-timers used for this type of ore is free-milling, which means that the gold could be extracted from the rock by crushing and panning, and did not require a chemical process to work them.

Most commonly, fine gold is 999. This is the gold most commonly referred to as 24 karat gold, although technically 24 karat gold is 100% pure. However, as this is difficult to achieve outside of a lab environment, 999 gold is generally considered close enough. Gold manufacturers are legally allowed a half-karat tolerance in making gold products.

When comparing gold associations (Table 4 and Figure 3) with gold recovery by amalgamation and cyanidation (Table 5), there is a correlation between increased gold exposure towards the finer fractions and a greater gold recovery (from 6.6 to 16.3%) due to the possibility of access to the cyanide solution, therefore the comparatively low rate of Au recovery is to be related to
