Methods and systems for processing an iron ore tailings byproduct are described. In one embodiment, a method for processing an iron ore tailings byproduct includes sizing particles within a slurry of the iron ore tailings byproduct to separate particles from the slurry having a dimension less than a predetermined size. After sizing, the method may further include centrifugating the particles less than the predetermined size into centrifugated concentrate and tails portions. The centrifugated concentrate portion may be separated into separated concentrate and tails portions. Finally, in certain embodiments, the separated concentrate portion may be dewatered to a remaining composition of matter comprising iron in greater proportion than in the iron ore tailings byproduct. Generally, using the systems and methods described herein, iron that would have otherwise been un-recovered is extracted from the iron ore tailings byproduct.
