Many of these minerals consist of metallic elements in chemical combination with the element sulfur. Most ores of important metals such as mercury ( cinnabar - HgS), iron ( pyrite - FeS 2 ), and lead ( galena - PbS) are extracted from sulfides. Many of the sulfide minerals are recognized by their metallic luster. Figure 10d-4: Pyrite.
