 — Unlike alluvial gold, which is found as very small flakes on river banks, gold-bearing rocks have to be dug out of the ground. We want pure gold, but gold-bearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals.

Remember, commercial operations end when it is no longer profitable. That does not mean when the gold is exhausted. Investigate areas near the site of former gold quartz ledges. Finding new areas of placer gold that have not been claimed is, in my opinion, "easier". Fine gold flakes can be found for many miles on waterways and their tributaries.

The collecting agent bonds to the gold, creating an oily film that will later attach itself to the surface of air bubbles. The organic chemicals prevent the gold from bonding to other material. Air is then passed through the solution and the gold-laden film attaches itself to the bubbles. The bubbles rise to the top and the gold is skimmed off.
