Minerals Most metals, including transition metals, are found in solid inorganic compounds known as minerals. Usually, these are oxides, hydroxides, sulfides, or carbonates. Minerals are named by common, not chemical, names (see Table 23.1) 3 Sphalerite ZnS Malachite Cu 2 CO 3 (OH) 2 Pyrolusite MnO 2 http://www.wrightsrockshop.com/gallery /under_50/50_gallery3.htm Cinnabar HgS http://www.chemical- engineering.co/2011/07/25/cinnabar/ http://commons.wikimedia.org/wiki /File:Greenockite-Hemimorphite- Sphalerite-285103.jpg
