Rutile has many significant uses. In beach sands, if there is a large quantity of rutile, it serves as an important component of heavy mineral sand ore deposits. These sand ore deposits are eventually extracted to get the rutile mineral for the production of refractory ceramic, titanium metal, and pigment.
The most obvious way to tell the difference between them is the specific gravity. When panning out material, gold will settle and concentrate in the bottom of the pan, but pyrite will move freely in the pan. You will often see them at the surface mixed in with the lighter sands and gravels.
