The presence of the critical and sought-after (semi-)metals gallium (Ga) and germanium (Ge) has previously been reported from mineralisations in the Bergslagen ore province, south central Sweden.
The latest and historical Indium Germanium Gallium prices graph and charts,China Indium Germanium Gallium metal export and import market data and news in Shanghai Metals Market(SMM). ... MMi Daily Iron Ore Report for May 15th 2020.
Gallium is conventionally obtained as a byproduct of aluminum, and germanium as byproduct of zinc processing. An exception to this rule is the Apex Mine ore which has served as the only primary source in the world for direct production of gallium and germanium.
Mineralogy. The bulk of meteoric iron consists of taenite and kamacite.Taenite is a face centered cubic and kamacite a body centered cubic iron-nickel-alloy.Meteoric iron can be distinguished from telluric iron by its microstructure and perhaps by its chemical composition also, since meteoritic iron contains more nickel and less carbon.. Trace amounts of gallium and germanium in meteoric iron ...

The Butler iron meteorite has been found to have a germanium concentration of 2000 parts per million, which is about five times higher than the highest concentration that has been measured previously in an iron meteorite. The gallium concentration is 87 parts per million, which is among the highest concentrations found in these objects. The nickel content is 16.0 percent, the second highest ...
This microprobe is an appropriate instrument to measure distributions of trace elements with a spatial resolution of 2 ltm. We demonstrated on the iron meteorites Cape York (Agpalilik), Toluca and Odessa that the elements copper, zinc, gallium and germanium imitate the profiles of nickel, in taenite lamella.
Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery blue metal at standard temperature and pressure; however in its liquid state it becomes silvery white.If too much force is applied, the gallium may fracture conchoidally.It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium ...
Gallium (Ga), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table. It liquefies just above room temperature. Gallium was discovered (1875) by French chemist Paul-Émile Lecoq de Boisbaudran, who observed its principal spectral lines while examining material
The nickel content of kamacite in hexahedrites and octahedrites has been found to vary within 3.3-5.8 per cent. The average of 4.7 per cent of all nickel values is lower than the heretofore reported figure of 5.5-6.0 per cent. In the light of the iron-nickel phase diagram the low nickel values in kamacite appear to point to the possible existence in taenite at its boundary with kamacite of ...

The concentrations of gallium, germanium, cobalt, chromium, and copper have been determined spectrographically in eighty-eight iron meteorites, including representatives from all structural classes, and in nine stony-iron meteorites. The analytical procedures and the structural characteristics of the meteorites studied are described. It is confirmed that concentrations of gallium in iron ...
The iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Iron was discovered by humans before 5000 BC. In its elemental form, iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth's crust and the most common element by mass forming the earth as a whole.

currently precipitates almost of the gallium, germanium, iron, lead, and other contaminate metals between a pH of 2.5 and 4.5. Purification consisted of precipitating gallium from the ion exchange strip solutions at pH 4.1 using sodium hydroxide. At pH 4.1, the germanium, iron, lead, cadmium, aluminum, copper, and some zinc will also ...
Iron-Gallium Alloy (Galfenol) is a magnetostrictive alloy with applications in sensing and sonar. American Elements manufactures iron-gallium in varying compositions and forms such as powder, plate, rod, wire, and sputtering target.
Gallium, germanium prices fall in buyers' market Gallium and germanium prices inched down as deals were heard and sales were made below Metal Bulletin's previous lows. Gallium prices fell to $125-155 per kg – the lowest level since Metal Bulletin has been pricing the metal – as the market continued to fall under the weight of overcapacity.
Therefore, to extract germanium and gallium from the ore, it is necessary to solubilize the iron compounds. Musto Explorations LTD, former owner of the mine, employed a 3-stage counter-current process using sulfuric acid and SO2 to leach approximately 80% of the germanium and 90% of the gallium from the ore (Olsen, 1989).

Both gallium and germanium exist as their separate or combined oxides that are associated with iron and silica (Liu et al., 2016a). The conventional process to recover Ga(III) and Ge(IV) involves treating zinc refinery residues by a combination of sulfuric acid leaching and solvent extraction ( Harbuck et al., 1989, Harbuck, 1993, Dutrizac et ...
