With reference to Cobalt production and uses, consider the following s...
 
  • Cobalt is an important ferromagnetic strategic alloying metal having irreplaceable industrial applications. It is a chemical element with the symbol Co and atomic no. 27. Cobalt is associated mostly with copper, nickel and arsenic ores. Cobalt is extracted as a by-product of copper, nickel, zinc or precious metals. Hence, statement 1 is correct.
  • Major use of cobalt is in metallurgical applications, in Special alloy/Superalloy Industry, in magnets and cutting tools industries. Cobalt is used as precursors (cobalt compounds) for cathodes in rechargeable batteries. Largest demand for cobalt has been from the Rechargeable Battery Industry. Hence, statement 2 is correct.
  • The world cobalt reserves are estimated at 7 million tonnes of cobalt metal content. Cobalt reserves are mainly in the Congo (Kinshasa) which contributes (51%) to the total reserves followed by Australia (20%). Besides, major reserves are also located in Cuba (7%), Philippines & Russia (4% each) and Canada 3%. Hence, statement 3 is correct.
  • Presently, there is no production of cobalt in the country from primary cobalt resources. The demand for cobalt is usually met through imports. Refining capacity of cobalt in India is estimated at about 2,060 tonnes per year. Hence, statement 4 is correct.
  • Occurrences of cobalt are reported from Singhbhum district, Jharkhand; Kendujhar and Jajpur districts, Odisha; Jhunjhunu district, Rajasthan; Tuensang district, Nagaland; and Jhabua & Hoshangabad districts, Madhya Pradesh. Cobalt occurring with nickeliferous limonite/laterite in Sukinda area, Jajpur district, Odisha and copper slags produced by HCL are two possible sources of cobalt. The seabed multimetal nodules which contain 0.3% Co (Av) along with other minerals are the other sources of cobalt.

1. Cobalt Production and Extraction:
- Cobalt is extracted as a by-product of copper, nickel, zinc or precious metals.
- This means that cobalt production is dependent on the mining activities of these primary metals.

2. Cobalt Uses:
- Major use of cobalt is in metallurgical applications such as special alloy/super alloy, magnets and cutting tools industries.
- Cobalt's unique properties make it a valuable component in various industrial applications.

3. Cobalt Reserves:
- Cobalt reserves are mainly found in the Congo which contributes around 51% to the total reserves worldwide.
- The Democratic Republic of Congo is a major player in the cobalt market due to its abundant reserves.

4. Cobalt Production in India:
- Presently, there is no production of cobalt in India from primary cobalt resources.
- India relies on imports for cobalt, highlighting the country's dependence on external sources for this critical metal.
In conclusion, all the given statements are correct. Cobalt's production, uses, reserves, and the lack of production in India are important factors to consider in the global cobalt market.
