Molybdenum is a refractory transition metal used primarily as an alloying agent in steels, cast irons, and superalloys, and secondarily in catalysts, lubricants, and specialty chemicals. World mine production reached an estimated 260,000 metric tons (Mo content) in 2024, a 6% increase from 248,000 metric tons in 2023. China dominates global supply at approximately 42% of world output (110,000 t in 2024e), followed by Peru (16%), Chile (15%), and the United States (13%). Of the five major producers — China, Peru, Chile, the United States, and Mexico, which together provide 90% of global supply — only China and the U.S. operate both primary molybdenum mines and byproduct copper operations. The remaining major producers extract molybdenum entirely as a byproduct of porphyry copper mining.

The U.S. molybdic oxide reference price averaged $41.72/kg in 2024 (13% below 2023's $47/kg and well off the 2022 peak of $54.32/kg), while production increased — a combination suggesting supply growth outpaced demand. U.S. mine production of 33,000 metric tons exceeds domestic apparent consumption of approximately 12,000 metric tons, making the United States a net exporter with E-category import reliance. Recycling of molybdenum from ferrous and superalloy scrap contributes as much as 30% of apparent Mo supply, a significant secondary flow for which no separate refining process exists — the Mo content of recycled alloys is reused in-situ. World reserves total approximately 15 million metric tons, concentrated in China (39%), the United States (23%), Peru (13%), and Chile (9%).

A significant structural risk is emerging from the byproduct supply side. As porphyry copper mines — which collectively provide the majority of global Mo output — experience declining ore grades and approach end-of-life, byproduct Mo recovery per unit of copper production will decline. USGS notes that several large porphyry copper mines are expected to reach end-of-life in the mid-2030s, potentially tightening Mo supply unless primary Mo mine expansions or new deposits fill the gap. Molybdenum is not designated as a critical mineral by either the United States (2022 list) or the European Union (EU CRMA), reflecting U.S. net-exporter status and globally diversified supply, but the medium-term byproduct dynamics warrant monitoring. Clean energy infrastructure and global power generation projects are expected to sustain demand for molybdenum-bearing high-strength steels and corrosion-resistant alloys.
