This shouldn't be a physical change as, the gold isn't being turned from it's liquid form to it's solid form. When we filter the water for gold flakes, we are essentially taking small amounts of gold from the water and collecting them together to form a larger and more apparent amount. No state change (ie, liquid to gas. Gas to liquid. Liquid to solid.) is taking place during the process.

Because the salt solution is monophasic; filtering is applied when a precipitate exist.
