Cold Bonding of Iron Ore Concentrate Pellets Mineral

Oct 26, 2010· Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and grate kiln furnac However, heat induration requires tremendous quantities of energy to produce high quality pellets, and is consequently expensive Cold bonding is a low temperature alternative to heat induration Pellets can be cold bonded using lime, cement, sponge iron powder.
