Sampling..part 2

After filling each of the pans. Riddick walks them down to the river and begins the process of washing the material down. He wants to settle out the sediment from the rock. The top pan is screened, so that as he uses the river water to agitate the material the sediment drops through the screen and into the pan below.

Gold is very dense, therefore it's greater weight causes it to fall to the bottom of all the concentrated sediment...usually just called concentrate.

Once Riddick screens all the rock out, he checks the top screen pan for large chunks of rose quartz, garnet, or if we are lucky enough a big old chuck of gold!

Than he uses the bottom pan and starts the process of panning it out for the gold.
