    1 Sulfurizing Reagent Oxidized ore is generally formed by ionic bonding, and is highly hydrophilic. It is not easy to float oxidized ore with xanthate collectors. After sulfuration with sodium sulfide, a highly hydrophobic sulfide film is formed on the surface of the oxidized ore. This film is easy to act with the xanthate collector, which makes oxidized ore activated and then floated.
