Abstract
In this study, we suggest proceeding to an experimental study concerning the synthesis of new organo metallic product xanthate (KIBX) by intermittent method and their use in the processes of sulphides flotation. The adsorption of potassium isobutyl xanthate (KIBX 3 ⋅10 -3 M) on sphalerite has been studied using electrochemical potential, FTIR technique and SEM. Non activated minerals and minerals activated with copper sulfate (10-4 M) and copper nitrate (10 -4 M) have been investigated at pH 7.5. Surface species have been identified by FTIR and correlated with SEM. After copper sulfate activation, copper xanthate exists on all of the minerals studied. Neutral pH is the most suitable for potassium isobutyl xanthate adsorption on sphalerite.
