· To search for tiny particles of gold in rivers, a mixture of sand, mud, and gravel is scooped up in a pan and swirled around. Gold particles are heavier than the other particles, so they settle to the bottom of the pan. The lighter particles stay suspended in the water, and are decanted (poured off).
