Sintering is a widely used method to agglomerate iron-containing fine-grained materials. In sintering the ore fines, concentrates, fluxes, and coke breeze are thoroughly weighed, moistened, and mixed. The sinter mix is fed on the grate of the sintering machine to make a 0.3-1 m high bed. The grate is an endless strand of slowly moving pallets.
