Put the rock powder in a mining pan. A mining pan has holes in the bottom of it like a colander. Because gold is heavy, it will sink to the bottom of the mining pan even while it's submerged in water, while the other minerals wash away. Pour a layer of rock powder onto the mining pan so you can extract the gold pieces.
