  • Size-dependent kinetics of iron ore reverse .

    Flotation experiments under pH 10.5 were performed using quartz/hematite artificial mixtures. The influence of particle size and monoamine unit consumption on the kinetic parameter was analyzed, in a fundamental level. The coarse quartz class was between 212 µm and 600 µm and the fine class was between 74 µm and 212 µm. Hematite particles were graded between 32 µm and 74 µm. .

    Abstract. Due to gradual depletion of high-grade iron ores, there is a need to investigate the treatment of low-grade iron ores. Current procedures are time and cost intensive. Batch laboratory scale reverse cationic flotation was employed to concentrate low-grade Fe ore, found in fluorspar tails in the form of hematite. This study used two types of depressants (soluble starch and dextrin) and ...
