To provide an ore flotation method that can suppress effectively the flotation of iron pyrite and/or silica mineral, and a method for recovering copper.SOLUTION: The present invention provides a method that applies the ore flotation technique to ore comprising copper mineral, and at least one mineral of iron pyrite and silica mineral. Slurry mixed with the ore is blended with iodine, causing the copper mineral to float while suppressing the flotation of the at least one mineral.SELECTED DRAWING: None 【課題】黄鉄鉱及び／又はシリカ鉱物の浮遊を有効に抑制することができる浮遊選鉱方法および、銅の回収方法を提供する。【解決手段】銅鉱物と、黄鉄鉱及びシリカ鉱物のうちの少なくとも一種の鉱物とを含む鉱石に対し、浮遊選鉱を行う方法であって、前記鉱石が混ぜ合わされたスラリーにヨウ素を添加し、前記少なくとも一種の鉱物の浮遊を抑制しながら銅鉱物を浮遊させる。【選択図】なし
