Which one of the following is a non-ferrous metallic mineral resource?
Which one of the following is a non-ferrous metallic mineral resource?
Solution
Option 1: Manganese -> Though technically not iron, manganese is typically grouped with ferrous metals as it's primarily used in steel and iron alloy production.
Option 2: Iron ore -> This is a ferrous mineral as it contains iron (Fe) as the primary metal.
Option 3: Lead -> This is a non-ferrous metal that does not contain iron and is used in batteries, radiation shielding, and various industrial applications.
Option 4: Cobalt -> This is also a non-ferrous metal, though it's sometimes used in steel alloys, it doesn't contain iron as a base element.
Hence, Option 3 (Lead) -> Lead is a classic example of a non-ferrous metal, meaning it contains no iron. Non-ferrous metals like lead, copper, aluminum, zinc, and tin are valued for properties like corrosion resistance, conductivity, and malleability that differ from ferrous metals -> correct
