This article introduces an efficient aerated infiltration heap leaching method for secondary sulfide copper ores.
Zhengzhou Jinquan Mining Equipment specially developed this method for high-clay copper ores, which traditional leaching techniques struggle to process.
First, we lay an impermeable layer between the yard base and retaining berms.
Then, we install liquid collection pipes and a gravel layer in sequence.
After that, we place aeration pipes before we stack the ore.
Finally, we carry out the leaching process to extract copper effectively.
During the stacking of high-clay ores, we pre-embed aeration pipes inside the heap.
These pipes efficiently deliver air deep into the ore pile.
As a result, they maintain sufficient oxygen throughout the entire heap.
Meanwhile, we adopt an infiltration leaching method.
This method keeps high-clay ores soaked in leaching solution for a long time.
In this way, leachate, air, and ore particles stay in full and continuous contact.
Therefore, the leaching reaction proceeds smoothly and efficiently.
This innovative technique makes heap leaching feasible for high-clay secondary sulfide copper ores.
It overcomes the poor permeability and low oxygen supply that plague conventional heap leaching.
Moreover, it greatly improves the leaching efficiency of copper resources.
In addition, it expands the usable scope of low-grade and high-clay copper ores.
Ultimately, this method enhances overall resource utilization and brings better economic benefits for mining operations.
