The ratio in the output from the three main pelletizing technologies changes depending on practical circumstances, such as iron ore reserves, iron ore types, market demand, and required investment. The ratio for grate-kiln pellets has increased to 55.33% in 2011 from 7.21% in 2000, while the ratio for shaft furnace pellets has dropped to 42.05% ...

Poorni and Natarajan (2013) investigated the role of B. subtilis, and the adaptation of B. subtilis, in the beneficiation of a de-slimed bauxite ore. In flocculation trials, corundum-adapted B. subtilis cells were able to facilitate the removal of approximately 96% of iron after 5 min interaction at pH 7 to 9.

Microwave-assisted magnetizing roasts were used to produce an iron ore product from low-grade, goethite-dominant, iron ore plant rejects. Goethite was found to be converted to hematite at temperatures above 370 °C on reduction in a microwave furnace under gas mixtures of 30:70 and 40:60 CO/CO 2. Reduction to magnetite occurred at …
