【Abstract】 In this test,the effects of magnetization treatment for depressor CK on floatation behaviors of pyrite and chalcopyrite were investigated with pure minerals.The depression mechanism of pyrite on magnetization treatment was studied with contact angle test and the absorption of xanthante on the surface of mineral.Comparing with routine floatation,magnetic field can strengthen the depression of pyrite.And magnetic field can increase the absorption of the depressor CK on the surface of pyrite,and increase the hydrophilicity of pyrite.更多还原
