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).
