Relatively little information is available in the literature regarding the speciation and solubility of Ga, Ge, In and Sc in aqueous solutions, especially at elevated temperatures and pressures. In this paper we critically review stability constants for relevant aqueous complexes of these metals and solubility products for relevant solid phases. Most of the …

Project objectives are to 1) assess the overall life cycle of selected byproduct critical elements tellurium (Te), indium (In), gallium (Ga), and germanium (Ge), 2) perform an assessment of critical element resources and examine the processes and conditions controlling the concentration of byproduct critical elements by deposit type, and 3) …

3 The Elemental Geochemistry of Ga 3.1 Gallium in Meteorites. The first estimate of the solar abundance of Ga was approximately 2.36 (normalized to 10 12 atoms of H), obtained by Goldberg et al. ().However, the emission line of Ga was quite perturbed and the estimate was based on complex solar atmospheric models, so this value should …

The present article provides information on uses, mineral resources and production methods of gallium and germanium. Both of these metals are used in advanced technology. Gallium is mainly used in the production of high-speed computer chips (integrated circuits) and optoelectronic devices. Germanium is employed as …

The paper summarizes data on germanium and gallium concentrations in natural magmatic melts as follows from analyses of mineral-hosted inclusions and quench glasses in volcanic rocks. Germanium concentrations in melts vary from 0.96 to 17.6 ppm (1472 determinations). The geometric mean germanium concentration in silicate melts is …

The geochemistry of gallium and germanium was studied in geothermal waters from the low-temperature fields in the Southern Lowlands and the Geysir hightemperature field in Iceland. Germanium concentrations in waters with temperatures below 225°C were in the range <0.05-24 ppb whereas those of gallium lie in the range of <0.01-21 ppb.

Indium (In), gallium (Ga), and germanium (Ge) are metals important in new energy technologies, and use of these metals is expanding dramatically. 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 …

Of the many trace elements commonly found in sphalerite, gallium (Ga), germanium (Ge) and indium (In) are currently the most relevant. This is due not only to their interesting geological behaviour (e.g. Cook et al., 2009 ), but also to their growing usage in certain high-tech applications such as smartphones (Ga, In), fibre-optic cables …
