Freeport-McMoRan Inc., often called Freeport, is a mining company based in the Freeport-McMoRan Center, in Phoenix, Arizona. The current company was created in 1981 through the merger of Freeport Minerals, formerly Texas Freeport Sulphur Company and McMoRan Oil & Gas Company, becoming Freeport-McMoRan Inc. Early history Freeport Sulphur Company was founded July 12, 1912 by the eldest son of Svante Magnus “E.M.” Swenson, banker Eric Pierson Swenson, with a group of investors, to develop sulfur mining at Brian Mound salt dome, along the US Gulf Coast.[3] Freeport, Texas was also established in Nov. 1912 to house workers, and serve as a port for Houston, rivaling Galveston and Corpus Christi.[4][5] Freeport mined sulphur along the Gulf Coast using the Frasch Process, the patents for which had expired in 1908.[6] Previously, Union Sulphur Company founder and patent-holder Herman Frasch had enjoyed a monopoly on the process.[7] The company became known as Freeport Sulphur, later changing its corporate name to Freeport Minerals. In 1922, Freeport started producing sulphur from Hoskins Mound in Brazoria County, Texas.
