Processing High-Grade Concentrates from Challenging Low ...

03/07/2013  Magnetite and hematite and their intermediaries may be present in low-grade ores due to dilution by plentiful massive waste rock occurrences or banded formations. Fe and non-Fe mineral complexes with the iron oxides such as sulfides, Ti, Mn and V minerals may present special challenges. In addition, elemental substitutions in the magnetite or hematite crystal lattice may lower the economic value of the final product after processing
