Decarbonizing Industrial Processes Using Renewable Hydrogen
Iron & Steel Making 12 Iron and steel making employs two interrelated processes: 1) Molten pig iron is produced from iron ore with coke in a Blast Furnace (BF). The Pig Iron is mixed with scrap metal and refined in a Basic Oxygen Furnace (BOF). 2) Solid metallic iron is produced in a Direct Reduction Iron (DRI). This iron is processedGet Price
Primetals focuses on green technology - heat processing
In the pre heating-oxidation unit, fine ore concentrate is heated to approx. 900 °C and fed to the reduction unit. The reduction gas H 2 is supplied over the fence from a gas supplier. A waste heat recovery system from the off-gas ensures optimal energy use and a dry dedusting system takes care of dust emissions from the processes involved.Get Price

Roasting (metallurgy) - Wikipedia
Roasting is a process of heating of sulphide 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.Get Price
