How do you separate gold and rock at home?
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.
What does fool’s gold look like in rocks?
Pyrite is called “Fool's Gold” because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak, while pyrite's streak is brownish black.
Will vinegar dissolve gold?

How do you test gold with baking soda?
Wash the stone in the baking soda/water mixture then rinse it in water and pat it with a paper towel. A reaction (dissolved line) shows that your sample has a lower purity, a slight reaction means that you've matched the Karat while no reaction indicates that you have a higher Karat gold.
What does vinegar do to gold?
Gold is unaffected by vinegar because it is a stable metal and will not react with oxygen. That means it will not change color, develop crystals, or disintegrate. If the sample is iron pyrite (Fool's Gold) or chalcopyrite, it may remain the color of gold, but will begin to form crystals while it is submerged.
