Hematite Processing by Flotation

Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves. Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of …

Use of Chemically Modified Nanocelluloses in Flotation of ...

The magnetite grade in the iron concentrate of the anionic flotation is increased up to 26.0% while the grade of non-metallic minerals is decreased to 1.2%. Hematite and magnetite liberation in both flotation tails is almost similar and equals 70% and 60%, respectively.

Flotation Machine Hematite Flotation Separator

The flotation of both minerals pretreated with MnCl 2 (Figures 3a and 3b) is severely affected by Mn and corn starch together, showing a synergetic effect (i.e. greater than the depression effects of both reagents separately), as presented in Figure 2 The addition of starch had a reduced effect on the flotation of hematite pretreated with MnCl ...

Nowadays, there are strong economical, ecological, and social incentives to develop novel green chemicals from renewable resources to reduce the environmental impact of processing. Cellulose, which is the most abundant natural polymeric source, offers one promising green alternative that could replace the present synthetic chemicals. In this study, two types of modified …

Effect of sodium alginate on reverse flotation of hematite ...

The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents consumption, the froth …

on the flotation of hematite using dodecyl amine report that hematite floats only above the iso-electric point, often quoted as 6.7. Other references give a wide pH range well below the iep of hematite, even as low as 0.8. It would appear that the mechanism(s) of the amine flotation of hematite is still to be elucidated. 1.
