Montana is The Treasure State, fitting for its rocks and minerals.
In 2016, these five states led the pack in mineral production, accounting for about one third of the total mineral production value for the entire country.
Also included is an analysis of the domestic mineral industry of the United States, along with summaries of state mineral production. So today, we thought we would share the top five mineral-producing states by value from 2016.
First up is the Land of 10,000 Lakes at number five. Minnesota slipped a place this year, falling from fourth overall in 2015. Iron ore is the primary mineral commodity by value in Minnesota, which leads the country in iron ore production.
California ranks number 4 overall, up two places from 2015. Californias unique contribution in the minerals world is boron, for which it is the only producing state in the United States. Considering that the United States and Turkey lead the world in boron production, Californias contribution is significant. Borons primary use, at least domestically, is in glass and ceramics, where it helps the glass or ceramic survive intense heat. For this reason its used a lot in glassware for baking and laboratory use.
