Cadmium, gallium, and germanium are metallic elements present in small amounts in various metallic mineral depos- its, their associated mine tailings, and in coal ash. Based on many mining company requests regarding information on cadmium, gallium, and germanium ocurrences in ia,
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.

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.
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.
The post-transition metals or p-block elements are extremely soft low melting metals that include the semi-liquid metals gallium and indium, tin, thallium, lead, bismuth, radioactive polonium, germanium and antimony. They are used extensively in the formation of various electronic and optical crystalline compounds. Metalloids
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.
The Iron Age had begun. Some kinds of iron were clearly superior to others depending on its carbon content, although this was not appreciated. Some iron ore contained vanadium producing so-called Damascene steel, ideal for swords.

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 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.

Gallium arsenide has a similar structure to silicon and is a useful silicon substitute for the electronics industry. It is an important component of many semiconductors. It is also used in red LEDs (light emitting diodes) because of its ability to convert electricity to light. Solar panels on the Mars Exploration Rover contained gallium arsenide.
PDF | 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 ...
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.
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.
