The use of filter aids on iron ore fines
Vacuum filtration is commonly used for dewatering of iron ore fines, and as with all filtration processes performance decreases with particle size Significant improvements are possible with the use of filter aids, usually anionic surfactants and flocculants The filtration and separation characteristics of iron ore fines have been investigated The experimental work included: characterization, evaluation of suitable flocculants to enhance settling and dewatering rate, determination of optimum dosages of flocculants, and influence of surfactants on nitration dewatering of both flocculated and unflocculated iron ore fines by vacuum filtrationThe Effect of Flocculants and Surfactants on the Iron ore Pelletizing: Fuel oil filtration Pelletizing is the process through which iron ore fines are transformed into an agglomerated form called “iron ore pellets” suitable for use in an ironmaking furnace at a steel mill, such as a blast furnace or electric arc furnacePelletizing Plants BOLLFILTER
