The distribution of gallium, germanium, cobalt, chromium ...

Gallium and germanium groups The gallium contents of iron meteorites are plotted against the nickel contents in Fig. 2. It can be seen that the observation of GOLDBEBG, UCHIYAMA, and BBOWN (1951) to the effect that gallium levels are concentrated in several well- separated regions, is fully confirmed.

Copper, zinc, gallium and germanium distributions in ...

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. The interpretation of the Zn, Ga and Ge profiles leads to the conclusion that these elements undergo diffusion mechanisms comparable to those of Ni.

iron (10%), zinc (17%), copper (0.4%), germanium (0.4%), silica (1.0%) and lead (15%). The metals for the residue are typically found as oxides although there are significant unreacted zinc sulfides. This residue was typically sold for the germanium value. Until recently, no revenue for the gallium was obtained from the sale of the residue.

Germanium Gallium Ore Leaching with Sulfuric Acid

The Apex Mine near St. George, Utah, USA, is the only ore body in the world which has been mined primarily for germanium and gallium within the last ten years. From 1880 to 1945, copper was extracted from this unique property, leaving behind unmined iron-rich minerals containing germanium and gallium.

Gallium - Wikipedia

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.

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 neighbours silicon and tin.Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.

The distribution of gallium, germanium, cobalt, chromium ...

Abstract 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.
