I flot 2 conc Cu and Co. Xanthate in return water is activating the Co in Cu flot, which we don’t need . Any ideas how to destroy Xanthate in return water . I’ve tried ozone expensive but works

Pass the water through activated carbon.  UV also works and heat.  Nothing will be cheap given the volumes usually involved.  Best bet is to put it to tails and recover it from there letting sunlight do its job if possible.  There is another possibility and they did this at Noranda back in the day, use some finely granulated activated carbon and add it to the mill or before the float circuit as a reagent.  The amount will be small and it can such up a lot of free reagent.  Careful not to let it take up the reagents you are adding.  Another option is to complex the xanthate with copper sulfate. You will have to measure carefully to make sure you are not making the problem worse.  Hope this helps and if you need any help with this let me know.
