Anthracite iron combined those experiments and the new hot blast processing. In the United States, where the Lehigh Coal & Navigation Company (LC&N) had begun shipping anthracite to Philadelphia in 1820 because the principles could not obtain sufficient fuels for their iron works at "the 'Falls of the Schuylkill' "—so had built the Lehigh Canal and taken over the works of the haphazard Lehigh Coal Mine Company—by the late 1820s having established works that were running smoothly, after building America's second operating railroad in 1827, they'd great interest in exploiting the great anthracite deposits of Schuylkill County for ironmaking, which mills foundries
Anthracite power-generation. The rarer higher grades of anthracite are purer – i.e., they have a higher carbon content – and are used in steel-making and other segments of the metallurgical industries. Technical characteristics of the various grades of anthracite are as follows: Anthracite is divided by size mainly into applications that need lumps (typically larger than 10 mm) – various industrial processes where it replaces metallurgical coke, and domestic fuel – and those that need fines (less than 10 mm), such as sintering and pelletising. The common American classification by size is as follows: Lump, steamboat, egg and stove coals, the
