The Edison Ore-Milling Company was a venture by Thomas Edison that began in 1881. Edison introduced some significant technological developments to the iron ore milling industry but the company ultimately proved to be unprofitable. Towards the end of the company's life, Edison realized the potential application of his technologies to the cement industry and formed the Edison Portland Cement Company in 1899.
