Probe arrangement for a flotation cell

A method, comprising

• analyzing material in a container comprising slurry and/or froth and/or gas and/or a transitional area between the froth and the slurry, using at least one probe comprising together a plurality of electrodes capable of being in contact with the material, the analyzing further comprising:
• a. injecting currents or voltages through at least two electrodes;
• b. measuring voltages or currents, respectively, through the electrodes;
• and
• c. determining conductivity distribution for the material using model based calculations, which comprise reconstruction of a vertical conductivity profile among the material.

A system for analyzing material, comprising:

• a probe arrangement of at least one probe comprising together a plurality of electrodes capable of being in contact with the material in a container comprising slurry and/or froth and/or gas and/or a transitional area between the froth and the slurry;
• a current source configured to inject currents or voltages through at least two electrodes;
• measuring means configured to measure voltages or currents, respectively, through the electrodes;
