Abstract:
| Indium (In), germanium (Ge), and gallium (Ga) have unique chemical and physical properties. This makes them critical for a wide variety of high technology, pharmaceutical, metallurgical and chemical industries. This extended abstract consists of three parts. The ?rst part covers In, Ge, and Ga in terms of their physical and chemical properties, ore mineralogy and uses. The second part summarizes available information on global reserves and resources and production. The third part introduces major deposit-types from which In, Ge, and Ga are recovered, focusing on volcanic-hosted massive sulphide (VHMS) and sediment-hosted massive sulphide (SHMS) deposits. For the purpose of this paper, SHMS deposits include syngenetic or early diagenetic sedimentary exhalative (SEDEX), Mississippi Valley-type (MVT), and Kipushi-type deposits. |
