[DOC] [TLE] Pig iron - Wikipedia [PAR] Pig iron. Pig iron is the intermediate product of smelting iron ore. It is the molten iron from the blast furnace, which is a large and cylinder-shaped furnace charged with iron ore, coke, and limestone. Charcoal and anthracite have also been used as fuel. [DOC] [TLE] Blast furnace - Wikipedia [PAR] A blast furnace is a type of metallurgical furnace used for smelting to produce
