Iron Ore Analysis & Process Optimization Solutions ...

Decreasing ore grades of existing or new iron ore deposits require predictive solutions to efficiently sort and blend iron ore for optimal and profitable beneficiation and downstream processing. Elemental and mineralogical composition as well as predictive models for the upgradability, based on metallurgical parameters, such as washable constituents, play an important role for iron ore producers.

Iron Ore – MSK

Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke, usually with limestone as a flux. Charcoal and anthracite have also been used as fuel. Pig iron has a very high carbon content, typically 3.5–4.5%, which makes it very brittle and not useful directly as a material except for limited applications.
