Indium and gallium recycling, specialist and expensive Due to indium and gallium production being a by-product of processing ores, a growing global industry has arisen to recover the metals, either in a spent form from manufacturing processes or from recycling indium- and gallium-bearing scrap materials.
Several ores, such as the aluminum ore bauxite, contain small amount of gallium, and coal may have a relatively high gallium content. Health effects of gallium. Gallium is an element found in the body, but it occurs in a very small amount. For example, in a person with a mass of seventy kilograms, there are 0.7 milligrams of gallium in the body.
Hence it is slightly more abundant than silver or mercury. Indium is generally found in ores of zinc and is produced mainly from residues generated during zinc ore processing. Indium is a moderately toxic metal by inhalation and mildly toxic by ingestion. However, the exact nature of its human toxicity is not clearly understood.
Cobalt processing: Cobalt processing, preparation of the metal for use in various products. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal close-packed crystal structure. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face-centred cubic. The metal has 12

("Cobalt Processing," 2012) Indium and gallium are the metalloids of this group. Since they occupy periodic group XIII, the two elements are chemically similar to each other. Indium is used in the LCD displays for TV screens, computer, and smartphone screens. Gallium is most often used in semiconductors, in the form of gallium arsenide (GaAs).
Gallium is a soft, silvery metal, and elemental gallium is a brittle solid at low temperatures. Gallium arsenide is a III-V direct bandgap semiconductor (different from silicon). Where is Gallium and Gallium Arsenide Produced? The production of gallium metal is often connected with the processing …
64 GALLIUM (Data in kilograms of gallium content unless otherwise noted) Domestic Production and Use: No domestic primary (low-grade, unrefined) gallium has been recovered since 1987. Globally, primary gallium is recovered as a byproduct of processing bauxite and zinc ores.
Aside from ore, gallium can be obtained from such industrial sources as the Bayer process caustic liquor that is a byproduct of bauxite processing, flue dust removed from the fume-collection system in plants that produce aluminum by the electrolytic process, zinc refinery residues, gallium …
Yet we make a lot of effort to capture the gold and we don't want to throw any fine gold away as it can be so valuable. Before you get going too far, take a look at the following information about getting all the gold out of your black sands and producing a clean, saleable placer gold product. Take a look at amalgamation.....
Ore from the open pit will be transferred to an on-site beneficiation plant for upgrading to a concentrate. It will then be trucked 65km by private road to a rail siding on the Darwin-Adelaide railway and thence taken 1400km by rail to the Rare Earths processing and separation complex to be built at Whyalla.
Ga-rich electronic waste is an additional attractive Ga resource with a high content of Ga. New scrap containing GaAs is being successfully utilized, whereas substantial quantities of the old scrap and LED waste are still not utilized for Ga extraction. Efficient processing of the …

The first magnesium metal extracted from sea-water was produced by Dow Chemicals at their , Texas plant in 1948. The facility operated until 1998, but, presently, the only remaining salt water magnesium producer is the Dead Sea Magnesium Ltd. (Israel)—a joint venture between Israel Chemicals Ltd. and Volkswagen AG.
62 GALLIUM (Data in kilograms of gallium content unless otherwise noted) Domestic Production and Use: No domestic primary (low-grade, unrefined) gallium has been recovered since 1987. Globally, primary gallium is recovered as a byproduct of processing bauxite and zinc ores.
Gallium occurs in very small concentrations in ores of other metals. Most gallium is produced as a byproduct of treating bauxite, and the remainder is produced from zinc-processing residues. Only part of the gallium present in bauxite and zinc ores is recoverable, and the factors controlling the recovery are proprietary. Therefore, an estimate
Gallium gallium germanium ore ... 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.
Gallium is produced exclusively as a by-product during the processing of the ores of other metals. Its main source material is bauxite, the chief ore of aluminium, but minor amounts are also extracted from sulfidic zinc ores (sphalerite being the main host mineral). In the …
Gallium rarely occurs in minerals except in trace amounts. Bauxite and the mineral sphalerite, as well as coal, often contain gallium as an impurity. No gallium is mined; it is obtained as a by-product of mining and processing other metals, notably aluminum, zinc and copper, and is produced in any nation that produces these metals.
Jul 01, 2008· Indium and Gallium: long-term supply . 01 July 2008 Gregory Phipps, Claire Mikolajczak and Terry Guckes. The high cost of crystalline silicon has kept system prices high, and given cheaper, thin-film materials an extra boost in the credibility stakes.
Source of gallium. Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin.
Chapter 2. Production and Processing of Aluminum 2.1 Extraction of Aluminum The extraction of aluminum from its ore and subsequent processing into finished prod-ucts takes place in a series of successive operations, each largely independent of the other. Generally the various processes are carried out at different plant sites. A summary of
