Consider the following minerals and their uses:
1. Titanium → Used in Paints and Enamels
2. Zircon → Television screens
3. Garnet → Imitation jewellery
Which among the above is / are correct matches?
Over 80 per cent of world’s titanium is derived from beach sand minerals ilmenite and rutile. India accounts for 15 per cent of the global titanium output. Over 50 per cent of titanium dioxide production is used to manufacture pigments in lacquers, paints and enamels. The dioxide, which absorbs ultraviolet light, is used in sunscreen lotions as well Titanium’s non-reactive property makes it ideal to be used in the human body for orthopaedic use. Titanium is used instead of steel as the metal is 45 per cent lighter than steel, and twice as strong as aluminium.
Zircon is used as foundry sand, in television screens and in the chemical industry. It is widely used in the ceramics industry. It is also used in leather tanning and paper coating industry, and in modern superconductors due to its high melting point. Garnet is a good abrasive and is used as a replacement of silica in sand blasting. Mixed with high pressure water, garnet is used to cut steel. Sillimanite rocks are used in the glass industry and in alumina refractories. (Down To Earth)
