Humans are significantly impacting their natural cycling. Mining and smelting appear to be currently the largest sources of these metals to the environment, primarily because In, Ga, and Ge are byproducts of lead and zinc mining. The life cycle .

Germanium - Wikipedia

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms ...The mineralogy of GalliumThis list of minerals containing Gallium is built from the mindat locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Gallium mineral species.mp-32: Ge (cubic, Fd-3m, 227) - The Materials ProjectGe is diamond structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Ge is bonded to four equivalent Ge atoms to form corner-sharing GeGe4 tetrahedra. All Ge–Ge bond lengths are 2.50 Å.Compilation of Gallium Resource Data for Bauxite DepositsCompilation of Gallium Resource Data for Bauxite Deposits By Ruth F. Schulte and Nora K.
