Therefore, to fully utilize the water circulation in the plant, the pre-soaking dehydration operation is required to be added.
If the high-copper raffinate cannot be completely utilized by adopting single-stage dehydration and the acid and the copper in the part of raffinate cannot enter the leaching process for utilization or circulation, the high-copper raffinate needs to be completely utilized by adopting two-stage dehydration, so that the acid and the copper in the high-copper raffinate can be returned to the leaching process for utilization or circulation, the acid consumption is reduced, and the copper metal is fully recovered.
The traditional configuration of the filtration and dehydration operation before the second-stage leaching is as follows: the configuration in workshop is divided into three layers, and filter cake transports the rubber belt conveyor setting at 0.00m plane, and the filter cake rubber belt conveyor of unloading sets up at the mid-plane, and horizontal pressure filter sets up at the last plane, and filter cake transports the filter cake to the pulpifying tank in stirring leaching workshop to the rubber belt conveyor of transporting, and production practice tests show that this scheme has following shortcoming:
(1) in the production process, due to the fact that the water content of the filtered filter cake fluctuates and the influence of viscous materials, the materials on the belt surface of the conveying rubber belt and the bottom plate of the funnel are bonded and agglomerated in the process of multiple times of transportation, and the hidden trouble that the logistics are not smooth exists.
(2) The filter cake transporting belt conveyor spans two workshops, and equipment and civil engineering investment are increased.
