The ore is finely ground, then put through froth flotation to separate minerals from gangue (on the property of hydrophobicity), to get a zinc sulfide ore concentrate consisting of about 50% zinc, 32% sulfur, 13% iron, and 5% SiO 2. Roasting converts the zinc sulfide concentrate to zinc oxide: 2 ZnS + 3 O 2 → 2 ZnO + 2 SO 2
