Copper-Lead-Zinc ores
In some cases, maximizing bulk copper recovery may require use of thiocarbamate and thionocarbamate collectors in conjunction with dithiophosphate and xanthate chemistries in bulk flotation. The zinc reporting to the bulk flotation tails feeds the zinc circuit which is operated as previously described in the lead-zinc flotation section.
