Question

______ has very less percentage of iron.

विकल्प

• Magnetite

• Lignite

• Hematite

• Siderite

Answer 1

Siderite has very less percentage of iron.

Explanation:

siderite is an inferior, low-grade iron carbonate mineral (FeCO₃) with a very low percentage of iron usually less than 40% to 48%. It contains many impurities, making large-scale commercial mining less economically viable than high-grade ores.
