Jan 20, 2017 The process of turning raw product into finished stainless steel is a lengthy one, but it can be simplified into six steps. Lets look at this incredible process. Making the Iron. To create pure steel, the products that go into it- lime, coke and iron ore- must be made into iron. This study presents the ore texture, mineralogy and whole rock geochemistry of iron occurrence from the Edea North area located at the upper limit of the Nyong Unit, part of the Congo craton. This iron mineralization is of magnetite quartzite type enclosed by metamorphic rocks of the granulite facies. Two main facies have been identified over the study area including the banded and the massive ...

kinetics for reduction of iron ore based on the phase

The hot potassium carbonate process has been used effectively in many ammonia, natural gas, hydrogen, direct iron ore reduction, and ethylene oxide plants for many decades (Chapel et al., 1999). German patents using hot carbonate absorption of CO 2 can be found from as early as 1904 ( Kohl and Riesenfeld, 1985 ). This enables STEINERT to deliver value-added solutions throughout the entire process, from design and consultation through to manufacturing, installation and commissioning services. Since our founding, STEINERT has been a pioneer in mechanical mining separation and processing, e.g. ore sorting equipment. As a leading global manufacturer of ...
