This is any in which is from ore at a temperature below the melting points of the materials involved. Gangue remains in the spongelike product, known as direct-reduced , or DRI, and must be removed in a subsequent steelmaking Only high-grade ores and pellets made from superconcentrates 66 percent are therefore really suitable for DR making.
