Question

what is slab how it is separated from the metal​

Answer 1

Answer:

Slabs are constructed to provide flat surfaces, usually horizontal in building floors, roofs, bridges, and other types of structures. The slab may be supported by walls or by reinforced concrete beams usually cast monolithically with the slab or by structural steel beams or by columns, or by the ground.

Concrete generally has reinforcing steel rods embedded in it and during the crushing process the steel is broken into short lengths with very sharp points. The steel has to be removed before the concrete can be reused and the most efficient method of recovering the steel is through magnetic separators.
