While I probably only recovered about 1/4 oz of flakes (if that), I saved all my black sand (generally regarded as a waste by-product of gold panning) in kitty litter buckets. It is mostly Iron oxide Magnetite ore, and is much heavier than quartz sand, but less heavy than garnet, sapphire or gold, which are all recovered by the panning process, intentionally or not.
Saying all sand is magnetic or non-magnetic would be virtually impossible, or frankly, inaccurate. Most sand is created from a natural process called weathering, which could take anywhere from hundreds or millions of years to occur.
Non magnetic particles, such as gold, quartz, and pyrite, are not amenable to magnetic separation, but some magnetic material may be removed from the feed. For instance, in a few situations, plants using gravity concentration for recovering gold, used magnetic separators to remove the high concentration of magnetite that was recovered with the gold, prior to further processing.

One of the more common classes of ores containing gold is when gold is associated with pyrite, pyrrhotite, and arsenopyrite. This is the area of gold recovery that has probably received the most research and plant optimization support especially in light
Black sand has a specific gravity of from 5 to 11, or 5 to 11 times the weight of water. Gold, on the other hand, has a specific gravity of around 19 and platinum around 21. As you can see, gold and platinum can be two to three times the specific gravity of black sand, and this is why gold or platinum can be extracted from black sand ore.
