At present, the main flow treatment mode of leaching residue washing mainly comprises two modes of filter pressing washing and CCD countercurrent washing, wherein the filter pressing washing realizes solid-liquid separation of leaching residue and leaching liquid/washing liquid under the action of external pressure, can furthest reduce the external slag water content and reduce the metal loss taken away by solution, but has the defects of large filter pressing factory building, more equipment, high dependence on operators, large equipment maintenance amount and lower adaptability to smelting enterprises with high ore treatment amount and large slag amount, so the current filter pressing washing technology is mainly used for treating concentrate leaching residue. In comparison, the CCD countercurrent washing system has the advantages that the CCD countercurrent washing system is connected in a mode that a plurality of washing thickeners are connected in series, the flowing directions of overflow liquid and underflow slag are opposite, the first-stage CCD thickener is an underflow slag inlet and a washing liquid outlet, and the last-stage CCD thickener is an underflow slag outlet and a system washing water inlet. Under the normal and stable running state of the CCD countercurrent washing system, the liquid phase and the slag phase of each stage of thickener are balanced in and out, the overflow liquid at the upper part is clear, the solid particles are less entrained, the concentration of copper and cobalt in the liquid phase is gradually diluted in the washing process, the metal quantity of copper and cobalt in the solution taken away in the underflow slag is gradually reduced, and finally, the purposes of leaching slag washing and system copper and cobalt recovery rate are realized. The CCD countercurrent washing system has the advantages of simple structure, low labor intensity, large treatment capacity, high metal recovery rate and the like, and is widely applied to copper-cobalt ore wet smelting.

In actual production, if the internal material distribution structure of the CCD countercurrent washing system, especially the height of a clarification layer, is not mastered in time, the trend imbalance of the internal material of the thickener is easily caused, and finally the thickener is in mixed running, so that the normal and stable operation of the system is greatly influenced, and the metal recovery rate is reduced. Therefore, the actual thickness of the internal clarification layer of the CCD thickener is mastered in real time, the system parameters are timely adjusted according to the production conditions, early warning is carried out in advance, and the method is particularly critical to the stable control of the CCD countercurrent washing system.
