Design of Leaching Field for Copper Waste Ore
With the rapid development of metallurgical industry, large amounts of copper waste ore are continuously produced. In the process of mineral processing, it is difficult to separate the waste ore into metal and other minerals. With the improvement of smelting technology, the separation of waste ore has become an important part of mineral resources re-exploitation. Copper waste ore leaching technology is one of the advanced processes for mineral resources re-exploitation. In this paper, a copper waste ore leaching field is designed.
The leaching field of copper waste ore is mainly composed of leaching tower, acid leaching pool, scraping plate and foundation. The leaching tower is a cylinder with a height of 8 meters and a diameter of 4 meters. Its main function is to provide elevation difference and equipment support for leaching operations. The acid leaching pool is a closed-circuit pool in the middle of the leaching tower. It has a dry area at the bottom of the pool and a damp area moated by side walls. Before entering the pool, the copper waste ore needs to be crushed into particles smaller than 1 cm. The motor connected to the stirring device inside the pool is used to mix the ore particles and the acid. The scraping plate is installed at the bottom of the leaching tower. Its role is to guide the ore particles to flow into the acid leaching pool.
The leaching field designed in this paper strictly follows the requirements of operating environment and communication. The leaching tower is equipped with a ring channel which is used to control the ascent and descent of acid. Because the acid leaching pool is located in the center of the tower, the acid has to be transported to different leaching areas through the ring channel, and then the spent acid is collected and recycled.
In terms of safety protection, the leaching field designed in this paper has considered the potential impact of external factors such as climate change. It is equipped with a water tank of 1000 cubic meters to provide rainwater for the whole field, so that it can maintain the normal operating temperature and pressure of the system. The whole leaching field is surrounded by high-supported wall which can minimize the possibility of external intrusion and make the leaching process more secure.
To sum up, the leaching field design of copper waste ore complies with environmental protection regulations, meets operation requirements, provides reliable safety protection and ensures the efficient operation of the system. This design can be used as an example to provide a reference for the design of future leaching fields.
