stages in limestone processing
A Day in the Life: What Goes On at a Quarry – MDLPA
Limestone Processing. Limestone processing begins with cutting the material. Some limestone blocks are cut into slabs before reaching the fabrication stage. Other limestone deposits are crushed and sent to be made into concrete, other materials for use in construction applications, crude oil, etc. Building and Construction

Blast furnace process
Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent. The carbon is fed to the blast furnace in the form of coke ( pyrolyzed coal) from the coking plant.
