Metallic: Softer than glass: 3 perfect cleavages at 90 degrees, high density. Hematite: Metallic or nonmetallic luster: Hard to tell, but harder: Redbrown streak. Hornblende: Nonmetallic (black) Harder than glass: Usually black or dark green; 2 cleavages at 60°/120° (56°/124°) Biotite: Nonmetallic (black) Slightly harder than glass
However, nonmetallic elements are more plentiful than metallic elements The key difference between metallic and nonmetallic minerals is that metallic mineral is a bination of minerals that can be melted to gain new products whereas nonmetallic minerals are a bination of minerals that do not produce new products on melting.
