Abstract
A movable belt conveyor system for a leach pad for use for sulfidic copper ore, where favorable conditions are to be generated for leaching out the copper by a slight compaction of the ore piled up into a dump for the microbiological leaching technology. The movable belt conveyor system of a length of up to several km is composed of a plurality of smaller belt segments, comprising a tail segment (70), standard segments (711-n) and a head segment (72), as well as a traveling tripper (8). To prevent the loading by these individual components from being excessively compacted by the weight of the device during multiple travel over the dump during the moving process, the belt drives with the driving drum are accommodated in the tail element (70), which is supported on the soil next to the leach pad. In addition, the traveling tripper (8) is designed as an independent unit with the belt drums, additional belt drives and the belt-tensioning means, which unit is autarchically displaceable on a caterpillar-type moving gear (85) of its own. Due to the moving of the belt on the caterpillar-type moving gears of the standard segments (711-n), on the head segment (72) and on the traveling trippe…
