Empty your pot, melt some of the suspect lead and cast a couple of bullets. If the bullets shrink away from the side of the bullet mold, resulting in misshapen bullets, you have zinc in the lead.
As to sorting out the zinc wheel weights from lead alloy wheel weights, they will float on the top of the lead as it melts before the melt gets hot enough to melt zinc, and may be skimmed off. Some have a "Z" ro Zn" on them.
