  • Composite iron pellets and methods of making same
    Patent number: 11530464
    Abstract: Disclosed herein are methods and compositions for producing composite pellets comprising a core comprising: iron ore and a carbonaceous reducing agent; and a shell comprising: iron ore; and having a core and shell transition in a manner such that no visible boundary exists between the core and the shell in a cross-section of the pellet. The methods can be used to produce composite pellets with improved productivity and quality, and the resulting composite pellets can be used to produce direct reduced iron (DRI).

  • Coated iron ore pellets and a process of making and reducing the same to form reduced iron pellets
    Patent number: 10550445
    Abstract: Iron ore pellets including a core comprising iron ore, a first coating comprising lime, and a second coating comprising cement, wherein the first coating is disposed between a surface of the core and the second coating. A process for manufacturing the iron ore pellets whereby the first coating is applied to the core to form a coated core, the surface area coverage of the first coating is measured, the second coating is applied to the coated core, and the surface area coverage of the second coating is measure. A process for manufacturing reduced iron pellets is also provided whereby the iron ore pellets are reduced with a reducing gas at temperatures up to 1100° C.
