Cold Bonding of Iron Ore Concentrate Pellets Mineral

Cold Bonding of Iron Ore Concentrate Pellets Mineral

Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and grate kiln furnaces. 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, and

Iron processing. Mostly it appears in iron carbon alloys such as steels, which contain between 0.003 and about 2 percent carbon (the majority lying in the range of 0.01 to 1.2 percent), and cast irons with 2 to 4 percent carbon. At the carbon contents typical of steels, iron carbide (Fe 3 C), also known as cementite,
