Sintering. Sintering involves mixing the iron-bearing material such as ore fines, flue dust, or concentrate with fuel e.g., coke breeze or anthracite. 10 The mixture is then spread on surface beds which are ignited by gas burners. The heating process fuses the fine particles, and the resulting product is lumpy material known as sinter.
