COBALT

  • Cobalt
  • Mines Producing Cobalt

The metal cobalt was discovered by George Brandt in Sweden in 1735, although it was used as cobalt salts in the ancient civilisations of Mesopotamia and Egypt for giving glass a deep blue hue. Brandt had been trying to prove that the blue colour given to glass had in fact been caused by a new element, cobalt, rather than that of bismuth, that was often found in the same places at cobalt. In nature it is a silver grey colour and has magnetic properties much like that of iron. Its artificially produced isotope cobalt-60 is used in the sterilisation of medicine and foods. It is also invaluable to human existence as the only metal that exists in vitamins (vitamin B12). Cobalt is also used as a catalyst in many industrial processes.


Most Cobalt is Recovered as a Lead, Nickel or Copper By-Product
Although cobalt can be made in a laboratory, this is not necessary, as it is available commercially as many ores contain it. However, many of these ores are not economically important therefore cobalt is produced commercially as a by-product from the processing of lead, nickel and copper ores.


Cobalt has many uses, some of them are as follows:
Cutlery and jewelery is coated with cobalt with an electroplating technique to create hardness and give them a resistance to oxidation.
Porcelain enamel ground coats are made from cobalt.
Cobalt-57 is used in medicine to discover the amount of vitamin B12 in a person's body.
Cobalt-60 is used in medicine as its gamma rays are able to sterilise medical objects, food etc. and for measuring density.
Cobalt compounds are used in industry as catalysts to quicken chemical reactions such as in liquid fuels and polymers.
Cobalt can be added to alloys to create super-alloys. These super-alloys keep a stable temperature and therefor find wide use in gas turbines and jet engines. It is also used in the manufacturing of prosthetic joints, some false teeth and permanent magnets.
It is used to create certain colours in inks, varnishes and paints.
Lithium cobalt oxide is used in lithium batteries. It is also used in re-chargeable NiMH batteries.
Cobalt-59 can be used to create a nuclear bomb. The explosion would be relatively small but the surrounding area would remain radio-active for a considerable time.


Australia has Large Cobalt Mining Project at Mt Thirsty in Western Australia
Australia has the worlds fourth largest Cobalt ore deposit at the Mt Thirsty Cobalt Nickel Manganese mining project 20 kilometres northwest of Norseman in Western Australia. The Mt Thirsty Project has the potential to become one of the worlds top ten cobalt producers as it will have a capacity to produce 3,000 tonnes of cobalt a year during its first three years of production.


The Mt Thirsty deposit differs from other Western Australia deposits as it is completely oxidised and has a low clay content. This will facilitate the using of cheaper atmospheric leaching process that won't require more expensive and problem proned autoclaves. The ore body at Mt Thirsty can also be extracted without the need for blasting and most of it is shallow, no more than 15 metres below the surface.
