Zinc:

  • It is found in association with lead and silver.

  • Also used for dry-batteries, white pigments, electrodes, textiles, die-casting, rubber industry,

  • And for making collapsible tubes containing drugs, and pastes.

  • Rajasthan is the leading producer of zinc accounting for about 99 per cent of the total

  • Production.

  • India imports about 80 per cent of its requirements from australia, canada, russia, and zaire.

Tungsten:

  • It obtained from the wolfram ore.

  • It is a self hardening mineral and therefore, used in steel industry, manufacturing of ammunition, armour plates, heavy guns, hard-cutting tools, etc.
