Sponge Iron Ore: A porous form of iron made from reducing an iron oxide at such low temperatures that melting does not occur; usually derived from the purification process of coal gas.
Spent Iron Sponge is liable to heat and to spontaneously ignite, especially if contaminated with oil or allowed to attract moisture, when it may emit toxic fumes. It also emits a strong odour, and its dust particles mixed with the right proportion of air are liable to cause a dust explosion.
It is essential that this commodity be cooled after its manufacturing process and weathered for at least eight weeks prior to shipment. Sintered Iron Ore: Partially fused finely powdered iron ore submitted to heat.
