Another difference between biomass fuels and fossil fuels is bulk handling properties and how they behave during milling. Coal mills are designed to handle hard and brittle materials whilst biomass fuels are fibrous and often rather soft. The biomass particles can be significantly larger than coal particles and still burn out completely, so the

Integrated Mills: The principal raw materials for an integrated mill are iron ore, limestone, scrap, and coal (or coke). These materials are charged in batches in a blast furnace where the raw materials are converted to liquid iron (also called pig iron). The material is then moved to a basic oxygen furnace (BOF) for final chemistry refinement.
