2021-9-7 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. This separation and concentration of copper and moly is
