metallurgy of iron class 12 pdf

This belt rotates around two wheels in which one of the wheels is magnetic, and therefore the magnetic particles get attracted to the magnetic wheel and fall apart from the non-magnetic particles. The compounds of metals mixed with soil, limestone, sand, and rocks are known as minerals. Principles of Metallurgy, Class 12 Chemistry NCERT Solutions.
