Copper Lead Zinc ores

As described in the lead zinc process description in some instances enhanced iron sulphide depression can be improved by aeration prior to the differential Cu Pb flotation step Most often the copper minerals are floated after galena depression.

Lead Zinc ores

Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit typically lime is used to raise pH for iron sulphide depression The flotation collectors used in sphalerite flotation tend to be less powerful because sphalerite at this stage typically readily floats and using a more aggressive collector can float more non sphalerite minerals.
