Raw Material Mining and Quality Control for Steel ...

As iron occurs only as iron oxides in the earth’s crust, the ores must be converted, or ‘reduced’, using carbon. The primary source of this carbon is coking coal. Coal is a key raw material in steel production. Coal is primarily used as a solid fuel to produce electricity and heat through combustion. Coke, made by carburising coal (i.e ...

2008-9-1  The iron ore is predominantly mined by opencast mining throughout the country. The solid material generated in large quantities by iron ore extraction is the material that overlies the ore body and the processed tailings . These wastes contain minerals associated with the ore body and host rock, mainly the laterite, and sometimes the clays.

What are Uses of Cast Iron - Application - Material

2 天前  Gray cast iron is the oldest and most common type of cast iron. Gray cast iron is characterised by its graphitic microstructure, which causes fractures of the material to have a gray appearance. This is due to the presence of graphite in its composition. In gray cast iron the graphite forms as flakes, taking on a three dimensional geometry.
