The Effect of Grain Size on Microwave Interaction of Magnetite Concentrate Mixed with Carbonized Biomass Waste

摘要

Aims: In this study, microwave interaction of magnetite ore concentrate whichwas mixed with carbonized biomass waste and divided into different grain sizes, wasstudied.Materials and Methods: The mixture consisting of magnetite concentrate and carbonizedproduct was pelletized by the addition of molasses and jelly as binders. The pellets preparedwith various particle size powders were subjected to microwave treatment at differenttimes.Results: Temperature of the pellet produced with powders between -212 +150 μm grainsizes and -45 μm were measured as 837.5°C at 304th second and 945.9°C at 210th secondrespectively.Conclusion: Although there was a large temperature difference between the core and thesurface of the pellet, a high degree of metallization was observed in these samples.
