Most Common Concentrates. Most gold-pan concentrates consist of relatively dense, iron-based minerals such as magnetite (iron oxide, ferrous-ferric), hematite (iron oxide, ferric), ilmenite (iron titanium oxide), and chromite (iron chromium oxide), all of which have substantial specific gravities. between 4.3 and 5.3. Their generally dark colors are the origin of the term “black sand.”
