Froth stabilization (3 replies and 4 comments)

What would cause froth to destabilize? Xanthates are being used as a collector. Would the presence of hydrocarbons in ore (due to oils and grease from machinery) have an effect?

Hello,

What do you mean destabilize? Do you have photos? Describe what you see please.

hi, I can't take photos of the process. It basically starts out as a uniform layer of froth and after some time it starts to separate, forming gaps in between such that you can see the aqueous layer.

Froth destabilization can be caused by a couple of factors. To name a few; It can be due to too much xanthate into the system, low feed RD, too much air injection into the circuit while operating at low levels, if senkol is one of the reagents that you are using too much of it can also cause froth destabilization. Hydrocarbons (oils etc) would not really cause distabilization as it is an immiscible liquid.

Thanks. I since found out that it can be a number of factors as you have mentioned. I suspect the xanthates in this case. I think one can do a process of elimination and look at all possible factors for improvement. Thanks for your response

Hi Thabiso,
Can you please share more on Senkol. We switched over from AM810 to Senkol and have been struggling to have a stable froth and froth that gets to cover the entire cell

Is this similar to what you are seeing?
