Many important metal ores are sulfides, in which metals are bonded to sulfur. Significant examples include galena (lead sulfide), sphalerite (zinc sulfide), pyrite (iron sulfide, sometimes called "fool's gold"), and chalcopyrite (iron-copper sulfide). Sulfides are well known for being important ore minerals.
