Abstract
A mineral processing method capable of efficiently separating a copper mineral from a molybdenum mineral is provided. The mineral processing method includes: a conditioning step of adding sulfite as a surface treatment agent to a mineral slurry containing a copper mineral and a molybdenum mineral; and a flotation step of performing flotation using the mineral slurry after the conditioning step. The hydrophilicity of the copper mineral can be selectively enhanced by sulfite, so as to be able to produce a difference in hydrophilicity between the copper mineral and the molybdenum mineral. Therefore, the molybdenum mineral can be selectively caused to float, and the copper mineral and the molybdenum mineral can be efficiently separated from each other.
