Description

Technical Field

[0001] This utility model relates to the technical field of tailings dam return water volume control devices, and in particular to a mobile tailings dam return water chute volume control device. Background Technology

[0002] After the raw ore enters the concentrator and undergoes crushing, grinding, and beneficiation processes, the valuable minerals in the ore are separated, while the tailings are discharged as a slurry into the tailings pond for storage. When the tailings slurry enters a water body, its flow slows down, and the tailings begin to settle. As the clarification distance increases, the supernatant water gradually becomes clear. After a period of settling, the clearer water can be recycled; this water is called tailings pond return water. The recycling of tailings pond return water can significantly reduce the water resource procurement and treatment costs for mining enterprises, directly improving economic efficiency. At the same time, effective management of tailings pond return water also helps reduce wastewater discharge, maximizing resource utilization and protecting the environment.

[0003] There are generally two methods for extracting tailings pond water: gravity flow water extraction, which utilizes the terrain's elevation difference to allow the water to flow into the collection system by gravity; and pump-suction water extraction, which uses pumps to extract water from the tailings pond. Different extraction methods are suitable for different environments and needs. When using gravity flow water extraction, the tailings pond water enters the water extraction tunnel through the tailings pond water extraction chute and is then transported to the water extraction combination tank. From there, the water is transported to the mineral processing plant for recycling.

[0004] Due to the size of the tailings and weather conditions, the water level in tailings ponds typically fluctuates, causing the outflow from the tailings pond return water chute to change accordingly, making precise control difficult. The amount of return water used in the concentrator also fluctuates based on production changes. For return water management, the outflow from the return water chute is usually controlled by moving the chute cover. This method not only involves high workload for operators but also fails to provide precise control over the outflow from the return water chute. Utility Model Content

This solves the problem that tailings dam water levels typically fluctuate due to the size of the tailings volume and weather conditions, causing the return water chute flow rate to change accordingly, making precise control difficult.

However, this method not only involves high workload for operators but also fails to provide precise control over the return water chute flow rate.
