The present invention pertains to a production method for low-sulfur iron ore, wherein iron ore containing in excess of 0.08% but no more than 2% of sulfur is subjected to flotation, producing iron ore in which the sulfur content has been reduced to 0.08% or less. In this production method, during the flotation process, (1) a xanthate based compound and a salt of an amine compound are used as collectors, (2) a xanthate based compound is used as a collector, and a substance that releases sulfur ions in water is used as an activator, or (3) a xanthate based compound and a salt of an amine compound are used as collectors, and a substance that releases sulfur ions in water is used as an activator. |
