| 摘 要： | 通过浮选试验及脱附试验，研究不同矿浆温度下滑石表面上甲基纤维素脱附行为及其对滑石浮选的影响。结果表明，滑石天然可浮性较好，甲基纤维素对滑石具有一定的抑制作用，其抑制效果随矿浆温度升高而增强，水洗能够减弱甲基纤维素对滑石的抑制作用，使滑石浮选回收率升高，且低温水洗时滑石的浮选回收率增加更多。使用甲基纤维素能够实现黄铜矿和滑石的浮选分离。

| Abstract: | Through flotation tests and desorption tests, the desorption behavior of methylcellulose from the surface of talc at different temperatures and its influence on the flotation of talc were studied. The results show that the natural floatability of talc is good. The depressive effect on methylcellulose on talc is enhanced with the increase of pulp temperature. Washing can weaken the depressive effect on methylcellulose on talc, increase the flotation recovery of talc, and increase the flotation recovery of talc more at low temperature. The flotation separation of chalcopyrite and talc can be realized by using methylcellulose. |
