Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan.
For example, certain materials have an important recycling potential within a given environmental and economic framework and are not always considered locally as waste despite the legal definition of waste.
