The best metal ore minerals are those that contain large amounts of metals of value. Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides. Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are magmatic, hydrothermal, and sedimentary.
