How Scientists Use XRD to Analyze Minerals

How Scientists Use XRD to Analyze Minerals

 · The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous beltfed furnace. Sinter quality begins with the proper selection and mixing of ...
