| 摘要 |
The invention relates to a method and an apparatus for monitoring the quality of an ore delivered to flotation concentration and the state of a slurry prepared from said ore. In the method, two or more working electrodes (6, 7, 8) featuring a cross sensitivity are immersed in the slurry to be monitored and the differences of potentials between each pair of electrodes is measured, whereby no reference electrodes are needed. The working electrodes (6, 7, 8) may comprise an argentite electrode, a platinum electrode and a molybdenum electrode, in which case the following differences of potentials between electrodes are being measured: &Dgr;(Ag—Pt), &Dgr;(Ag—Mo) and &Dgr;(Pt—Mo). |
