Surface properties of copper

Even at optimum pH 6, over dosage of collector will negate flotation selectivity and recover copper as well as iron/lead/zinc. Also note how "letting go" of pH from 6 to 7 may have the similar effect on recovery as adding more collector and will less selectively recover more copper as well as iron/lead/zinc.
