mini-mill
Quick Summary
A minimill is a relatively small-scale steel mill that uses scrap metal as its starting material. This approach contrasts with traditional integrated steelworks that process iron ore. Minimills emerged after 1970, often built in industrial regions where scrap metal is readily available. They typically use electric-arc furnaces to melt scrap and then employ continuous casting to produce billets, which are then rolled into products like rods or wire. This method represents a more efficient use of resources by recycling existing metal.12
