<p>The invention relates to a method of and a device for monitoring the operation of a flotation cell. In the method according to the invention, the electrical conductivity of the material (3, 7) in the flotation cell (1) is measured to observe any variations in the movement, the properties and/or the inner structure of the material. The device (10) according to the invention comprises a number of measuring sensors (11, 12, 13, 14) of electrical conductivity, which are to be fitted in the flotation cell (1) and embedded in the material (3, 7) contained in it for measuring its electrical conductivity and, on the basis of the conductivity values, defining the state and/or the properties of the material.</p> |
