While we are all hoping to find that onceinalifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible.

Ore processing Waihi Gold

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation the size required for the cyanide to be able to see the gold in the leaching process.
