| 摘要 |
The invention relates to an apparatus and to a method for treating a liquid that contains ore material. The apparatus comprises an open tank (13) arranged to receive a mixture of liquid and ore precipitate, whereby in the tank filled with the liquid, light precipitate material is arranged to rise to the liquid surface, heavy precipitate material is arranged to sink onto the bottom of the tank (13), and purified liquid is arranged to be discharged from the tank (13) between the layers formed by the light precipitate material and the heavy precipitate material. A first electrode (10) is provided in the lower part of the tank (13), and a second electrode (11) that is movable close to the first electrode is provided above the tank, whereby the first (10) and the second electrode (11) form an electrolytic system that induces electroflotation in the tank filled with the liquid. |
