[Domestic iron ore market brief: Prices of iron ore concentrates in the Tangshan region may continue to be in the doldrums] The domestic ore market in Tangshan has recently been in the doldrums. The delivery-to-factory prices for 66% grade dry-basis iron ore concentrates, including tax, range from 920 to 930 yuan/mt. Recently, the two major local steel mills have had low intake volumes, and their just-in-time procurement operations have supported suppliers' willingness to ship. Additionally, local mine prices have risen, and surrounding resources are tight with firm prices.
