American Potash and Chemical Company (sometimes abbreviated as AMPOT) was a large chemical manufacturer in the United States from the 1920s through the 1960s. It produced various chemicals for US industry and the US military. It was bought by Kerr-McGee in 1967, which reformed it into the Kerr-McGee Chemical Corporation (KMCC) around 1970.[1][2][3][4][5][6]

It started by producing Borax and Potash from Searles Lake, CA. In World War II it diversified to other chemicals. In the 1950s it bought Eston Chemicals, Western Electrochemical, and the Lindsay Chemical Company and further diversified its product line. In the 60s it bought a large interest in Compagnie des Potasses du Congo. In 1967 AMPOT was bought by Kerr-McGee. Around 1970 Kerr-McGee reorganized and AMPOT became the KMCC which in 2006 was spun off as Tronox.[1][2][3][4][5][6]

When AMPOT bought the Lindsay Chemical Company it also got the Rare Earths Facility in West Chicago, Illinois.
