Abstract: To leach the metal, crushed ore must be dumped in relatively thin layers of a height of approx. 5 m to 10 m. A conveying and stacking system, including a movable conveyor belt system, traveling tripper and stacker is used for this. The movable conveyor belt system is formed by a plurality of individual belts, the so-called grasshoppers. Provisions are made in the dumping technology for a high block for the end device in the conveying chain, the stacker with its swingable stacker boom, to always discharge an arc-shaped layer of ore, after which the device moves back by the amount of the next layer to be discharged in an arc-shaped pattern. This process is repeated until the stacker has moved back by the effective length of a grasshopper. Conveying is then stopped, one grasshopper is removed from the conveyor belt system and dumping of the ore is then continued. To enable this technology to be used, the stacker must be provided with a material pickup area, which is as long as a grasshopper.
