    [photo, Lehigh Cement Company, Baltimore, Maryland] In 2015, Maryland ranked 35th among the 50 states for total nonfuel raw mineral production value at $306 million and accounted for 0.39 percent of the country's total production value. This was an increase from $277 million in 2014. As per estimates of 2015, portland cement represented the leading nonfuel commodity, followed by crushed stone and sand and gravel.
