The word "deposit" means a body of iron-bearing materials which, in accordance with good engineering and metallurgical practice, should be mined as a unit.
"Low-grade iron-bearing formations" mean those commercial deposits of iron-bearing materials, not including paint rock, located beneath the surface of the earth, which in their natural state require beneficiation to make them suitable for blast furnace use, and which, after such beneficiation, produce in tonnage less than 50 percent of iron ore concentrates from the tonnage of low-grade iron-bearing formations delivered to a beneficiation plant and which formations must be mined in accordance with good engineering and metallurgical practice to produce such concentrates.
"Beneficiation" means the process of concentrating that portion of the iron-bearing formations entering the beneficiating plant.
"Concentrates" means such ores which by the process of beneficiation have been made suitable for blast furnace use.
