Lead Zinc ores
Sphalerite that is rejected into the lead flotation tails is then floated in a second flotation step after activation with copper sulphate The copper ions replace zinc atoms on the sphalerite surface creating a pseudocopper mineral surface coverage on the sphalerite which is then collected using copper
