[Trump Announces $15 Billion Steel Plant Plan] According to Deep Tide TechFlow, on September 29, citing Jin10 Data, Trump officially announced a $15 billion steel plant construction project on the eve of the midterm elections, declaring it as the largest industrial project of its kind in U.S. history. The production facility will fully utilize locally mined iron ore from Minnesota as its core raw material, with a planned annual output of 10 million tons. This investment has been explicitly designated as a key demonstration project under the White House's current strategy to promote the reshoring of manufacturing. The related statement emphasized that the plan will effectively integrate upstream mining and downstream smelting processes, further strengthening the self-sufficiency and controllability of the U.S. domestic steel industry supply chain.
