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
