‘The most valuable animal in the world’: India’s pigments

Pigments are among the most valuable minerals in the planet’s oceans.

India’s top three pigments are magnesium oxide, which is used in making steel, and manganese oxide, used in glass.

India’s top five pigments, which include calcium oxalate, are also found in glass, cement, and metal.

The nation is currently developing the world’s first marine copper mine, which could be used to produce up to 300 tonnes of copper per year.

The government plans to build a marine copper-minerals refinery to produce copper for domestic and industrial use.
