Selective Flocculation of Dilband Iron Ore, Pakistan [PDF]

Mehran University Research Journal of Engineering and Technology, 2011
Selective flocculation for long is known as one of the beneficiation techniques applicable to the concentration of finely disseminated ores. The success of this technique is based on the selective adsorption of an organic polymer on the mineral ...

Impacts of flocculation on the distribution and diagenesis of iron in boreal estuarine sediments [PDF]

Biogeosciences, 2018
Abstract. Iron (Fe) plays a key role in sedimentary diagenetic processes in coastal systems, participating in various redox reactions and influencing the burial of organic carbon. Large amounts of Fe enter the marine environment from boreal river catchments associated with dissolved organic matter (DOM) and as colloidal Fe oxyhydroxides, principally ...

The flocculation performance of grafted sodium alginate and other polymeric flocculants in relation to iron ore slime suspension

European Polymer Journal, 2001
The flocculation characteristics of sodium alginate-g-polyacrylamide (grade VI) SAG-VI developed in authors’ laboratory was compared with some commercially available flocculants in aqueous suspensions of 0.5 wt.% iron ore slimes. Two varieties of iron ore slimes were taken, one is denser than other, for comparison.

Recovery of iron from iron ore slimes by selective flocculation [PDF]

Journal of the Southern African Institute of Mining and Metallurgy, 2017
The beneficiation of iron ore slimes by selective flocculation was studied. Polyacrylamide (PAM) and guar gum were used as flocculant, along with sodium hexametaphosphate (SHMP) as a dispersant. The samples collected were initially subjected for chemical and mineralogical studies.

Influence of particle properties on iron flocculation [PDF]

Water Supply, 2017
Abstract In this study, the importance of charge interactions during flocculation of Fe3+ in the presence of particles and anions/cations at various pH values was investigated. SiO2, (s) and ZnO(s) were dosed as particles to promote charge interactions and/or serve as a nucleus to accelerate floc formation. In the pH range 6–9, SiO2, (s)
