(PDF) The characterisation of magnetic materials extracted from …
After the magnetic separation, the black magnetic concentrate was obtained. The black color visually implies that iron oxide in the magnetic material is predominantly composed of the magnetite type [19]. However, further characterization is needed to support the identification of iron oxide types and the content of the iron sand magnetic material.
Distribution of Magnetic sands on Lake Michigan beaches near Milwaukee
Only natural beaches were sampled in this study; that is, beaches not artificially supplemented with sand. The study was concentrated at Doctors Park, located about 10 km north of Milwaukee, because this beach had high concentrations of black sand in 1998 that was concentrated near the ephemeral stream that flows to the lake across the beach.

Why is black sand magnetic?
Is magnetic black sand worth anything? By-product black sand from inland placering is often richer than beach sand. But generally, black sand, unless a concentrate, is not worth much effort. In any case, it is worth spending a dollar or two to have an assay made for gold of a carefully taken sample, not selected sand.
