Molybdenum (moly) is often produced as a byproduct of copper mining. Copper is used for electronics, construction, and metal alloys. Moly is mostly used to make metal alloys, and as a catalyst. As markets need copper and moly, their ores are separated, concentrated, and sold separately.

Mar 01, 2017Molybdenum disulfide's thinnest structure is only three atoms deep, with a central layer of molybdenum atoms linked to layers of sulfur on either side. This form was only discovered in 2011 and was originally produced, like graphene, by using adhesive tape to peel off a single layer though more recently by growing sheets on a silicon wafer.

Molybdenum is mined as a principal ore, and is also recovered as a byproduct of copper and tungsten mining. In 1913, Frank E. Elmore developed a flotation process to recover molybdenite from ores; flotation remains the primary isolation process today. Molybdenum is silvery with a gray cast, has the sixth-highest melting point of any element.
