Other Ventures Ore milling and Cement

Another Edison interest was an ore milling process that would extract various metals from ore. In 1881, he formed the Edison Ore Milling Co., but the venture proved fruitless as there was no market for it. In 1887, he returned to the project, thinking that his process could help the mostly depleted Eastern mines compete with the Western ones. In 1889, the New Jersey and Pennsylvania Concentrating Works was formed, and Edison became absorbed by its operations and began to spend much time away from home at the mines in Ogdensburg, New Jersey. Although he invested much money and time into this project, it proved unsuccessful when the market went down and additional sources of ore in the Midwest were found.

Edison also became involved in promoting the use of cement and formed the Edison Portland Cement Co. in 1899. He tried to promote widespread use of cement for the construction of low cost homes and envisioned alternative uses for concrete in the manufacture of phonographs, furniture, refrigerators, and pianos. Unfortunately, Edison was ahead of his time with these ideas, as widespread use of concrete proved economically unfeasible at that time.
