Depressants for Froth Flotation
Depressants are key in ore separation during froth flotation, either by inhibiting gangue to float the target mineral or by suppressing the target mineral to allow gangue to float. This selective depression is vital for complex, high-impurity ores. Depressants are crucial for maximizing yields and concentrate grades.
Our experts, with deep flotation process knowledge, have developed an efficient and versatile range of depressants. These technologies are effective at lower doses than traditional chemistries like water glass and CMC..
FFA-DLE
DEL is an effective inhibitor for sphalerite, pyrite, and marcasite. In the flotation process of a lead-zinc polymetallic ore, DEL can be used in combination with sodium sulfite and zinc sulfate, where the three have a synergistic effect. Adding a small amount of DEL significantly enhances the inhibitory effect of sodium sulfite and zinc sulfate on activated sphalerite.Suitable for the flotation of ores containing one or more of sphalerite, pyrite, and marcasite.
FFA-10N
Common inhibitors like water glass, CMC, starch, and guar gum can cause difficulties in concentrate filtration due to their high viscosity. The newly developed clay mineral inhibitor FFA-10n is not a conventional market combination, has low viscosity, and its pH can be adjusted. It is unaffected by temperature during flotation. FFA-10n has a strong inhibitory effect on altered minerals but a weaker effect on target minerals, offering good selective inhibition. The inhibitor acts quickly and effectively, making easily floatable vein minerals more hydrophilic without affecting the floatability of valuable minerals, significantly improving the concentrate grade.
