Iron Ore Agglomeration Technologies IntechOpen

May 18, 2017  Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
