effect of pulp density in froth flotation

Froth flotationis a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the wordflotationis also used in the literature to describe the process indensityseparation in which lighter microplastics float to the surface of a salt solution

how doespulp concentration and ph affect froth flotation

When the flotation density of the mineral, the material particles are larger, the use of thick pulp. When the flotation density is small, the mineral of fine grain and slime material is used thinner pulp. To meet the froth flotation requirements, the concentration of pulp can be adjusted by adding the required water and flotation agents

Therefore finer separations are produced, provided that the overflow pulp density is above a value known as the critical dilution, which is normally about 10% solids. Below this density, the effect of increasing rising velocity with dilution becomes more important than the increase in particle settling rates produced by decrease of pulp density

Secondly, although the main factors of the experiment are pH value and density, other properties during the flotation process such as ore pulp flow, amina flow, starch flow can also be an influence. Regarding the ore pulp density, when the ore pulp is thin, the recovery rate would be low, resulting in the better quality of the pulp
