The mining and beneficiation scale of Pulang Copper Mine is 12.5 million tons per year, making it the largest porphyry copper mine in Asia. The ore crushing system project is located in a primitive forest area, which belongs to a high-altitude and cold region (with an altitude of nearly 4000m), and has extremely high environmental requirements. It is the throat project of the entire Pulang Copper Mine, with a crushing chamber of 45mx14.4mx18.1m and the largest span in Asia.

The project department overcame various difficulties during construction in harsh environments, completed the contracted project on schedule, and ensured the timely and successful commissioning of the Pulang copper mine.

This project has been awarded the title of High Quality Engineering at the ministerial level by the China Nonferrous Metals Industry Association.
