hematite reverse flotation condition

Design and flotation performance of a novel

01-03-2020· Based on the surface difference of hematite and quartz in solution, a hydroxyl-containing polyamine cationic surfactant was designed and screened with the assistant of computer simulation (molecular dynamics (MD) simulation and density functional theory (DFT) calculation) to enhance the separation efficiency in the reverse flotation system of hematite ore.

The nature of hematite depression with corn starch

15-08-2018· In contrast to previous literature, contact angle and micro-flotation results indicate that, though corn starch is not changing the wettability of hematite during reverse flotation, it is hindering the adsorption of mono ether amine on the hematite surface, hence, preventing the surface of hematite from becoming hydrophobic.

Effect of EDTA on quartz and hematite flotation

Leaching of Fe 3+ from hematite and β-FeOOH depends on pH (7.5-12), temperature and EDTA concentration. However, this reaction is very slow, with an equilibrium time of 4 days) (Chang et al, 1983). Cruz and Lima (2015) studied the influence of Mn 2+ ions in water on reverse cationic flotation of an iron ore sample (44.7% Fe and 31.8% SiO 2).

Effect of sodium alginate on reverse flotation

Given the gradual increase in the chlorite content of hematite ores, pulp properties seriously deteriorate during flotation. The traditional anion reverse flotation of hematite cannot effectively eliminate the effects of chlorite, leading to a significant decrease in the total Fe (TFe) grade of the concentrate. In this work, the effect of sodium alginate on the reverse flotation of hematite
