mechanism of flocculants in iron ore vacuum filtration

Factors Affecting Filtration Rates and Cake Moistures

Here is a list of all Factors Affecting Filtration Rates and Cake Moistures in plants or laboratory de-watering systems and processes. Particle Size of Solids Generally the large the particle size, the higher the filtration rate in Kg/m2/h and the lower the cake moisture. However, the validity of the last statement depends on other factors, e.g. distribution specific gravity of solids, absence ...

Beginners Guide to Concentrate Filtration - Outotec

This is generally detrimental to filtration where the best results are achieved when the surface charge is a minimum. Where it is not possible to change the surface chemistry coagulants and flocculants can be effective in improving filtration rates. Flocculants can be effective on vacuum filters where the slurry can be handled gently.
