Gold is less valuable than Topsoil. Yet Gold is now valued more than Topsoil, and Forests. I'd rather ask "How does selective logging protect Forests?"
If gold bearing mass is rich enough, grinding and panning. If not rich enough, grinding, selective dissolution for gold and precipitation
Gold appears golden because it absorbs all colors of light except yellow, which it reflects. This selective reflection of light gives gold its characteristic color.
You can separate gold from a mixture of gold and zinc using a process called selective precipitation. By adding a chemical reagent that reacts with zinc but not with gold, the zinc can be precipitated out of the solution, leaving the gold behind. This process allows for the physical separation of the two metals.
