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.Iron ore - WikipediaOf the iron ore exported 38.5% of the volume was iron ore pellets with a value of $2.3 billion and 61.5% was iron ore concentrates with a value of $2.3 billion. The majority of Canada& 39;s iron ore comes from Nunavut and from Labrador along the Quebec and Newfoundland and Labrador border.An innovative process for direct reduction of cold-bound ...Successfully developed an innovative process of direct reduction of cold-bound pellets from iron ore concentrate with a coal-based rotary kiln, in comparison with the traditional direct reduction of fired oxide pellets in coal-based rotary kilns, possesses such advantages as: shorter flowsheet, lower capital investment, greater economic profit, good quality of direct reduced iron.

Introduction to Iron ore Pellets and Pelletizing processes ...

Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity 25 % to 30 % . Normally pellets are reduced considerably faster than sinter ...Use of iron ore fines in cold-bonded self-reducing composite ...The feasibility of producing Direct Reduced Iron from cold-bonded self-reducing composite pellets made from Anglo American Kumba Iron Ore Sishen upgraded slimes was considered on laboratory scale. Composite pellets were made by mixing Sishen upgraded slimes, coke and different binders using a pelletizing disc by addition of moisture.
