The Tecnored process is developed in Brazil. The process uses self reducing briquettes from iron ore and fine coal. These briquettes are cold bonded. Iron ore reduction in the self reducing briquettes is very fast. As a result Tecnored can limit the height of its reduction shaft and thus limits the mechanical load on the cold bonded briquettes.
