The Effect of Polymeric Flocculants on Settling and

Oct 23, 2006· The high molecular weight flocculants, namely, magnafloc (1011) superfloc (N 300) were used for comparative studies. The present paper reports the settling and filtration behaviour of iron ore slimes. The experiments show that sedimentation rate increases with increasing flocculant dose upto a certain limiting value.

The Effect of Flocculants and Surfactants on the

Aug 16, 2006· 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 filtration.

Studies on the effect of flocculant adsorption on the

Sep 15, 2011· The effect of anionic and non-ionic flocculants dosages on the electrokinetic zeta potential of iron ore tailings particles is shown in Fig. 4, Fig. 5 respectively at pH 6.5 and 10. The zeta potential measured in the absence of flocculant dosage at pH 6.5 and 10 are −12 and −26.5 mV respectively ().With the addition of anionic PAM flocculant, it can be seen in Fig. 3 that particle charge

Influence of surfactants on filter cake parameters during

May 15, 1998· The influence of certain surfactants on the dewatering of fine iron ore sludge flocculated with anionic flocculants has been investigated in a laboratory-scale vacuum filtration unit. The filtration data have been used in calculating the cake parameters from an integrated form of Darcy's law.

FILTRATION OF IRON ORE SLIME USING SYNTHESIZED CO

The present paper reports study on filtration of iron ore slimes using the co-polymer synthesized by grafting polyacrylamide chains on starch backbone. The efficacy of the synthesized polymer was tested for the filtration of iron ore slimes following flocculation. The filtration rate increases with increasing flocculant dosage.

Effect & Influence of Flocculants & Surfactants on

Experiments were conducted with the addition of several types of flocculants and surfactants. The filtration response of the slurries was studied in terms of the cake formation rate and the residual cake moisture. An analysis of the results is presented in ascertaining the role of flocculants and surfactants during filtration A specular hematite concentrate (67% Fe, 0.5%
