US mini-mill costs drop below integrated mill costs.but .

US mini-mills are typically higher cost. On an operating cost basis, US integrated mills are typically lower cost than their mini-mill peers. Scrap prices are tied to the marginal cost of hot metal production—meaning that the input for scrap-based steelmaking is typically higher than the average ironmaking bulks mix (n.b. iron ore, coal and coke).
