Agglomeration & Pelletization | PDF | Blast Furnace
After iron ore concentration, agglomeration is used to combine fine particles into durable clusters in the forms of pellets, sinter, briquettes or nodules. Two common agglomerated products are sinter and pellets. Sinter is produced from coarser iron ore fines mixed with other materials and improves blast furnace productivity. Pellets are made from very fine iron ore and are mainly …
