Gold Recovery 101. Gold recovery is a crucial part of the mining industry. Gold can be found in almost everything we see and touch; there are several important industrial uses for gold in electronics, dentistry, and aerospace; however, almost 80% of gold ends up being used for jewelry. While jewelry is the end of the road for most mined gold

Step 2 – Placing the Material on the Pan. The material you have collected should be enough to fill your pan – or at least three-quarters of it. More expert prospectors will be able to fill the pan to almost full, but doing so can cause some of the gold particles to fall off during the panning process.
