The Climax Stowmarket plant in the United Kingdom is one of the world’s premier production and conversion facilities for ferromolybdenum. The plant started the production of ferromolybdenum as Minworth Metals in 1950. In 1968, Climax Molybdenum Company, a subsidiary of Freeport-McMoRan, U.K. Limited purchased Minworth Metals and since then we have improved production processes and increased plant capacity. The Stowmarket plant is dedicated to being the highest quality producer. The efforts to meet and exceed customer requirements have been a prime focus resulting in many customer quality awards. The plant is certified to the Quality Management Standard ISO 9001, the International Environmental Standard ISO 14001, and the Health and Safety Standard OHSAS 45001. The plant has been awarded the Molybdenum Mark for responsible production in 2023.
