titanium metal one of the few materials that can be used in the human body for hip replacements and heart pacemakers. Zircon Zircon is the other major product of the mineral sands industry and is a co-product of titanium
Magnetic separation is generally a low cost method of recovery, unless high intensity separators are required. The electro-magnetic high intensity separators that produce 20,000 gauss; the rare earth magnetic separators are relatively inexpensive and can produce magnetic fields around 6,000 gauss.
We have this magnetite black sand in 5 lb, 20 lb, and 50 lb weights, which is made up of magnetite and hematite. We do not know the exact composition but we do know that it can be either, or both with other natural materials.
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.
