Minimising frothing in Flotation Plant Thickener (2 replies and 1 comment)

Can anyone help with minimising frothing in flotation thickeners? Frother in use is MIBC. Different options of adding carbon depressants in addition to flocculant have been trialed with no significant success.

This is a common problem when you are over dosing on frother in your fltation cells.  If you over dose you can see poor frothing in the cells, and then as it gets diluted heavy froth in the thickener.  So step one cut your frother dosing by half, you might see better froth action in the cells and less in the thickener.

I have also seen persistent froth on thickeners because of collector over usage in the flotation circuit. A thick "oatmeal" froth.

Cut reagents and wait...

It could take days for your thickener to clear up.

Yes its taking days but do know any defoamer that can be used to break froth?
