The commodities include industrial minerals and natural aggregates, as well as ferrous and nonferrous metals.
The estimated value of production of all industrial minerals was $56.6-billion, which is 63% of the total value of US mine production value.
Crushed stone was the leading nonfuel mineral commodity domestically produced, accounting for 21% of the total value of US mine production in 2021.
Metal mine production was estimated to be valued at $33.8-billion, or 23% higher than that in 2020. The main contributors to the value of metal mine production were copper (35%), gold (31%), iron-ore (13%) and zinc (7%).
The top producing states were Arizona, Nevada, Texas, California, Minnesota, Alaska, Utah, Florida, Missouri and Michigan.
