Chat Online +In a process for a selective flotation of a copper-lead-zinc sulfide ore the raw ore is ground and slurried with water and the resulting suspension is aerated with air to adjust a certain oxidation-reduction potential and is subsequently successively conditioned with so 2 , ca(oh) 2 , and collecting and frothing agents, whereafter a flotation of cu is effected.
Chat Online +Zinc, however, can be selectively recovered from the pyrite concentrate.If the pyrite concentrate was originally floated with starvation quantities of col- lector (typically 20 g / t ore feed), then a short aeration period (5 min), with adjustment of the p h to 10.5, activation with cu and addition of xanthate lead to selective zinc flotation.
