During the 1890s, Thomas Edison launched a New Jersey mining operation to address an iron ore shortage. He designed rock-crushing technology and an electromagnetic ore separator to extract low-grade ore from crushed boulders.
The Edison Ore Milling Syndicate, Ltd., was organized in London on February 24, 1898, to exploit Edison's ore milling patents in all countries except the United States and Canada. The company used Edison's patents and ore milling designs when developing iron deposits in the Dunderland River valley, near Mo, Norway.
In 1899, after a failed attempt at ore mining, Thomas Edison formed the Edison Portland Cement Company. At his plant, Edison combined his mining operation's rock-crushing technology with new machinery he developed, like a more efficient cement kiln.
